Have you ever been working late at night when, all of a sudden, the silence around you felt too heavy? You look up and see your coworkers going about their business—keyboard clatter, pages turning, the occasional cough. Everything's normal. But something still feels off.
Like something's been drained away. The air's thinner, the lights a shade dimmer. Then you lower your head and get back to work, shove the feeling aside, tell yourself you're just tired.
---
Emergency department, West City Hospital. My name's always jammed into the ugliest slot on the roster—Lin Mo, 2 a.m. to 8 a.m., officially called "training the new guy."
The day Typhoon "Whale" made landfall, I wasn't supposed to be on night shift. Around three in the afternoon, Sister Sun leaned in while changing in the duty room, smelling of bruise ointment.
"Xiao Mo, cover for me tonight? My daughter's got a fever, her dad's on a business trip, and the nanny called in sick." Sister Sun was a veteran nurse in the ER—forty-something, loud, quick-handed, had looked after me plenty.
I saw the two dark patches under her eyes and nodded. She patted my shoulder and pressed a pack of compressed biscuits into my hand. "Thanks. I'll buy you soy milk tomorrow morning."
By seven that night the typhoon was roaring. Branches outside whipped like lashes, rain hammered the glass. The ER lobby was packed, twenty-some people queuing at registration—fevers from the rain, windblown injuries, and two old men who'd tumbled down the stairs when the power cut killed the elevator.
Dr. Zhao was running off his feet, the back of his white coat soaked with sweat. Nurse Xiao Zhou jogged with the medicine cart, its wheels squeaking across the tiles. I sat behind desk No. 3, four charts stacked in front of me, taking calls, writing orders, and taking an old lady's blood pressure all at once.
At the far end of the hall, a TV hung in the corner of the ceiling, the local station broadcasting typhoon warnings. The anchorwoman said it would pass overhead around midnight, winds at Force 12. The noise was half-drowned by the crying and coughing in the lobby.
By midnight, the crowd had thinned. Dr. Zhao leaned against the nurses' station, chugging a bottle of water, the tendons in his neck twitching. He asked, "Holding up?"
"I'm fine."
"Youth is nice."
He crushed the bottle and tossed it. "I got a herniated disc by forty. You'll know when you're older." I didn't answer, just flipped to the next chart. A young guy with a glass cut on his hand, five stitches, sat on an observation bed scrolling his phone, the screen light washing over his pale face. His mother was slumped asleep beside the bed, still gripping his arm.
Two a.m. The wind outside changed tone—from a low moan to a sharp whistle, punctuated by the dull thud of something heavy hitting the ground. The whole building shuddered lightly. The water in the old water cooler's jug rippled.
Then the rain stopped. Just like that, in an instant, like someone hit the mute button. I was unwrapping gauze, a pair of forceps holding a bloodied cotton strip, and my ears suddenly went empty. No wind. No rain. Not even the distant wail of a car alarm down the street.
I looked up. Seventeen observation beds and eight IV spots in the hall—I counted later. In that moment, every single person froze. Dr. Zhao stayed mid-sip, the bottle hanging in the air. Xiao Zhou had the medicine cart tilted, one foot lifted, the wheels not yet touching down.
The kid on his phone had his thumb hovering a centimeter above the screen, frozen on a paused short video. His mother's pupils were fixed on a wall, unblinking. The whole ER looked like a Polaroid, the kind that's just finished developing.
My throat tightened. The forceps trembled in my hand. I tried to call Dr. Zhao, but no sound came out. There was a strange smell in the air—mothballs mixed with wet rust—drifting slowly from the far end of the corridor.
I turned my head. At the end of the corridor, beside the elevator doors, stood someone. A dark-blue raincoat, the kind they sell at convenience stores, hood pulled low over his face. The hem dripped. Drop by drop onto the tiles, each one clear as a ticking second hand.
He held a white slip of paper—a registration form. He walked toward me. No footsteps. The water beads slid off his raincoat, leaving a trail of dark dots on the floor behind him. But the dots didn't spread. They stayed pinned to the ground, like someone had drawn them with a black pen.
He stopped in front of my desk, about a meter away. I could see a sliver of chin under the hood—skin bluish, the corner of his mouth slightly crooked. He raised a hand and set the registration slip on the desk. Thick knuckles, black grime under the nails. Then he turned and walked back down the corridor. The dripping faded into the distance.
When he reached the end, turned right, and vanished, the sound came back. The wind started howling again, rain pounding the windows like beans. Dr. Zhao gulped his water. Xiao Zhou's wheels squeaked. The kid swiped his thumb, and a man in the short video burst out laughing.
What the hell.
I looked down at the desk. The registration slip was still there, half-soaked, edges curling. I picked it up and flipped it over.
Patient name: Lin Mo. Sex: Male. Age: 27. Department: Emergency Internal Medicine. Visit time: 09:30, August 13, 2026.
What's today's date? I pulled out my phone and checked the lock screen. August 12, 2:17 a.m. The visit time was tomorrow. I stood up clutching the slip, the chair legs scraping. Dr. Zhao turned. "What's up?" "Nothing. Gonna hit the bathroom."
I rounded the desk, forcing my steps steady. One of the fluorescent tubes in the corridor was flickering, buzzing every few seconds, my shadow stretching and shrinking on the floor. I reached the end of the corridor. Right was the stairwell, left the passage to the inpatient wing.
The floor was dry. I crouched and ran my palm over the tile—gray-white glaze, icy, not a trace of water. I walked back to where the raincoat man had stood and crouched again. Still dry. The registration slip was in my pocket now, damp, pressed against my thigh, cold as ice.
I stood by the stairwell door, dazed. Faint baby cries drifted from the wards upstairs, far off, as if through several walls. The stairwell light was motion-activated and off, the whole thing a black hole. Couldn't see a thing.
I went back to my shift. Dr. Zhao asked why I was so pale; I said low blood sugar. He handed me a chocolate bar. I unwrapped it, chewed twice, couldn't swallow, and spit it into a tissue.
Around four, the rain had let up, but the wind still blew. An uncle hit by a falling tree while riding his e-bike was brought in by ambulance—right leg fractured, covered in blood. My hands shook as I cleaned his wound. Dr. Zhao thought I was exhausted and told me to lie down in the break room for half an hour.
I didn't dare sleep. I sat on the folding chair in the duty room, all the lights on, phone brightness maxed. The registration slip lay under my phone. I must have read the writing on it dozens of times.
It was handwritten, blue-black ink, the strokes ending with a little hook flicking up and to the right. It looked oddly familiar, like I'd seen it somewhere. But my head was too heavy, like it'd been filled with lead. I didn't think much of it, just figured the night shift was messing with my eyes.
There was a printed barcode and a registration number next to it, same format as the slips the self-service machines in the ER printed. The only difference: no doctor's stamp.
Six a.m., first light. The wind had mostly died, the rain down to a drizzle. Before leaving, Dr. Zhao clapped my shoulder. "Get some proper sleep. Don't come in tonight—I'll talk to the director." I nodded. Packing up, I tucked the slip into my patient notebook and shoved it to the bottom of my bag.
Walking out the hospital gate, the cleaning lady was pushing her mop cart into the ER lobby. I heard her mutter, "How'd the corridor get so dirty? Someone tracked mud in..." I paused, didn't look back.
Home at seven-thirty. My roommate had already left for work. A note on the living room table: "Dumplings in the fridge, microwave three minutes." I pulled the notebook from my bag and flipped to the page with the slip. Empty. I flipped twice, then dumped everything out of my bag.
Phone, power bank, keys, half a pack of tissues, a pen. No registration slip. I leafed through the notebook front to back, shaking each page. Nothing.
I sat on the sofa for ten minutes. Outside, the sky was gray-yellow, that muddy color after a typhoon. The breakfast stall downstairs opened, the sizzle of dough sticks frying drifting through the window, mixed with the owner hawking "sweet soy milk, salty soy milk."
Everything was so normal it made me want to puke. Then I made a decision. I messaged the director asking for a day off, reason: "window leaking from the typhoon, needs fixing." He replied with a voice note, nasal: "Sure, rest up. You worked hard yesterday."
I turned off my phone, drew the curtains, cranked the AC to the lowest, and sat wrapped in a blanket on the sofa, staring into space. TV on, some rerun variety show, a bunch of people laughing and grabbing chairs. I'm not a coward.
Back in med school, during anatomy, I'd stay alone until ten at night, pushing the specimen jars of formalin back to storage myself. But the visit time on that slip made my spine crawl.
Tomorrow morning, nine-thirty. If I hadn't taken the day off, my normal schedule meant I'd be back on night duty tonight, then after the morning handover I'd stay at the hospital writing charts until noon. At nine-thirty, I'd be at desk No. 3.
I picked up my phone and texted Dr. Zhao: "Busy in the ER today?" Half an hour later he replied: "Not bad, just two fever cases. Hey, did you drop something last night? Xiao Zhou found a registration slip in the corridor with your name on it, dated today." I stared at the screen, my stomach turning. "Don't throw it away. Save it for me." "Sure, left it on the nurses' station. When are you coming for it?" "Tomorrow."
I put the phone down and pulled the blanket up to my chin. Outside it was fully bright now. Birds chirping, someone downstairs blasting Phoenix Legend. The AC vent blew cold air.
I closed my eyes, my head full of that bluish chin and crooked mouth under the raincoat hood. I fell asleep. I dreamed I was sitting at the ER desk, a long line in front of me, everyone in blue raincoats, hoods pulled low.
They said nothing. One after another they placed registration slips on the desk. Every one had my name. Every one had a different visit time.
I jolted awake. Phone said three p.m. Drenched in sweat, the AC leaving my hands and feet cold. I took a hot shower. Coming out, I saw a message from my roommate in the group chat: "Bro, you didn't go to work today? I passed your hospital—the road out front is flooded."
I replied, "Typhoon drainage clogged, probably." He sent a video. In it, the sloping road outside West City Hospital was under half a meter of water, two sedans submerged with only their roofs showing.
The hospital gate was half-closed, people in orange life jackets hauling sandbags. "Not the road," he typed. "I heard your hospital's first floor leaked. Part of the ceiling collapsed, water running from the second-floor pediatrics all the way down to the first-floor ER. The whole corridor's flooded."
I put the phone down and walked to the window, cracking it open. Wind rushed in, chilly. The evening sky burned orange-red, clouds torn into strips by the typhoon, like someone had scratched them with a fingernail.
I suddenly remembered the feel of the corridor tiles at dawn. Icy. Dry. No water. Yet last night the water dripping off that raincoat man—dot after dot, pinned to the ground, like drawn with a black pen. That trail of water behind him.
I turned back, killed the AC, pushed the window open. The damp air rushed in, smelling of wet earth and rotting leaves. I decided to go back to the hospital tonight. Not looking for trouble. I'd lost a registration slip with my name on it, and it was still sitting on the nurses' station. I had to get it back.
Eight p.m., pitch dark. Broken branches everywhere from the typhoon, sanitation workers loading them into trucks. I rode a shared bike, splashing through shallow puddles, detouring around the deep ones.
At the hospital gate, the side entrance was open, lights on inside. I locked the bike and walked in. The first-floor lobby was different from usual—the tiles freshly mopped, damp, sandbags piled in the corner.
A section of ceiling was tacked up with plastic sheeting, bulging, dripping water now and then. The air had a musty smell the disinfectant couldn't cover.
The ER was open, a few patients in the IV area, the nurses' station computer glowing white. Xiao Zhou was on duty and looked up, startled. "What are you doing here? Didn't you take leave?"
"Came for that registration slip." I walked over, keeping it casual. She picked up a white slip from the counter and handed it over. "Here, this yours? The cleaning lady found it in the corridor last night. Thought you'd dropped it somewhere."
I took it. The paper was ordinary thermal paper, edges slightly curled, with the registration info printed on it. Patient name: Lin Mo. Visit time: 09:30, August 13, 2026. Exactly the same as last night's.
But the one last night was wet, handwritten, blue-black ink. This one was dry, printed, neat characters. How did handwriting become print? I pinched the edge and flipped it over. Blank.
But the paper felt slightly thicker than thermal paper, like two layers stuck together. I quietly scraped the corner with a fingernail. Under the surface thermal paper was indeed a stiffer backing sheet, faint blue-black pen marks showing through.
"Where did the cleaner find it?" I asked. "The corridor, over there." Xiao Zhou nudged her chin toward the end of the hall. "Near the stairwell door. Said it was floating on top of a puddle." My scalp prickled.
"Puddle?" "Yeah, someone must've walked in wearing a raincoat last night, tracked a line of water across the floor. The cleaning lady was cursing about it all morning while mopping." Xiao Zhou scrolled her phone. "She even took a photo and posted it in the group, saying from now on patients should wear shoe covers in the rain..." She turned the phone to show me.
The cleaner's photo of the floor tiles. On the gray-white glaze, a line of dark dots stretched from the middle of the corridor to the stairwell door. The dots were evenly spaced, as if measured with a ruler. Each about five centimeters across, edges sharp, no smudging. Exactly what I'd seen last night.
"What happened to the water stains?" I asked. "Mopped. Took several passes to get them off. Once dry, those tiles were a different color from the rest. No idea what was so hard to scrub." Xiao Zhou pocketed her phone. "Why, what are you digging into?"
I folded the slip and tucked it away. "Nothing. Gotta go." As I turned, Dr. Zhao came out of the observation room. "Hey, Lin Mo, weren't you off today?" He walked over. "Perfect timing, help me look at this ECG. Old Zhang's machine keeps printing noise, I think the probe's shot."
I followed him into the observation room. An old man lay on bed No. 3, eyes closed, the ECG monitor's green line jumping. Dr. Zhao went on about the probe.
Out of the corner of my eye, I scanned the bed card: patient Zhang Fumin, male, 68, diagnosis upper respiratory infection. Normal. But I noticed an umbrella on the bedside table. Folded, blue, wet. Its tip rested on the surface, water dripping drop by drop into a small round puddle.
I turned my head, following the umbrella's direction. A woman stood by the bedside table, forty-something, hair pinned with a claw clip, gray jacket. Probably the patient's family. She was looking down at her phone, the screen light on her face. All normal.
But I noticed her shoes. Sneakers, white, a ring of dark water stains along the soles, like she'd stepped through puddles. Ordinary water stains have blurry edges, slowly evaporating—just like the irregular smears on her soles.
I tugged Dr. Zhao's sleeve, lowering my voice. "That family member—when did she get here?" Dr. Zhao glanced up. "Just now, the patient's daughter. Brought her dad in for a fever. Can't you see it's still raining outside?" I turned to the window. Water trails on the glass, thin, running down at an angle. It had started drizzling again sometime.
"Her shoes are wet," I said. Dr. Zhao looked at me like I was nuts. "Shoes get wet in the rain. Is that weird?"
"What about the floor?"
I looked down at the tiles. The observation room floor was light-gray PVC. Scattered footprints, half-dry, half-wet. I crouched to look. The edges were blurry, the water slowly evaporating. No dots. Completely different from the puddle in the corridor where the slip was found.
I stood up, heart beating faster. The woman was still on her phone, as if she hadn't noticed me watching. "Dr. Zhao, what were you doing at three a.m. last night?" I asked.
He blinked. "Three? On duty. You were there too, remember? We stitched up the fracture case together."
"Was there a moment of silence? Like everything suddenly went quiet, everyone froze..."
Dr. Zhao frowned, tilting his head in thought. "I don't think so. I remember three a.m. was chaos—the wind howling like a banshee outside. There was no quiet moment."
I pressed, keeping my tone casual. "So no one in a raincoat came through the corridor? You have no memory of that at all?" He shook his head blankly, thought hard for two seconds, then said firmly, "No. Really no. The raincoat people who came last night were all patients and family. I saw several. The 'kind' you mean—I never saw anything special."
I said nothing more.
Leaving the observation room, the woman looked up at me. Just one glance. Then lowered her head back to her phone. The corner of her mouth seemed to twitch.
I hurried out of the ER lobby, through the corridor toward the side entrance. The fluorescent tube was flickering, buzzing. Water stains on the floor, probably from the afternoon leak. I paused at the stairwell door.
The door was shut. The motion light off. Nothing in the dark crack. I pushed. It wouldn't open. Something seemed to be wedged against it inside. I pushed harder. A soft "thud" came through the crack, like something had been knocked over.
Then the door opened. The stairwell was empty. The motion light clicked on, white and glaring. Concrete floor, dry, cigarette butts and dust. Nothing there.
I closed the door and headed out. The side entrance opened onto a narrow alley, dim yellow streetlight, wet ground. I pulled the registration slip from my pocket and examined it under the light. With a fingernail, I peeled back the thin thermal paper along the edge.
The backing sheet came into view, and sure enough, there were words on it. Blue-black ink, crooked, exactly like the handwriting on that handwritten slip at dawn.
"You saw it."
Three words. Below, a scrawled arrow pointing to the visit time on the front. 9:30. I looked around. The alley was empty. An orange cat sat by the trash can, licking its paw. Cars passed occasionally on the distant road, tires hissing through puddles. I checked my phone. 8:47 p.m. I stuffed the slip back in my pocket and hurried toward the alley mouth. Halfway there, my phone buzzed. A text from an unknown number. "Don't come to work tomorrow."
I stared at those four words for five seconds. The number was local, but I didn't recognize it. I called back. Two rings, then hung up. Called again—off. I stood at the alley mouth, wind whipping drizzle into my face. The streetlight stretched my shadow long and flat, pooling on the ground like ink.
I rode home, replaying last night in my head over and over. The raincoat man, the registration slip, the frozen ER, the water stains on the floor, the paper I couldn't find anywhere in my bag, the cleaner's photo of the puddle, and now the handwritten words on the backing sheet in my pocket.
Home. My roommate was already asleep, one nightlight left on in the living room. I sat on the sofa without turning on the main light, spreading the slip on the coffee table, phone flashlight on.
Under the light, the words on the back were uncomfortably clear. "You saw it"—three characters, strokes forceful, the last one ending in a hook, like the writer's hand had trembled. I stared at that hook for a long time. The longer I looked, the more familiar it felt.
I got up and rummaged through my desk drawer, found an old notebook from last year's rotation training notes. Flipped to a page with "ECG lead placement diagram" written in blue-black ink, neat and tidy. That was my handwriting.
I compared it with the slip. The stroke structure of "You saw it" was different from mine—more scribbled, more cramped. But that ending hook, the way it flicked up and right, matched the curve of the last stroke when I wrote the character for "diagram". Exactly. Exactly the same.
No mistake. A habit from practicing calligraphy I'd never broken. I'd had that hook since childhood—my elementary school teacher even called me out on it.
I closed the notebook and leaned back in my chair. One a.m. The drizzle had stopped sometime, the moon slipping out through the clouds, pale light on the windowsill.
I sat in the dark, listening to my own breathing. Very clear. The whole apartment was so quiet I could hear the refrigerator compressor humming, and the wall clock's second hand ticking. Tick. Tick. Tick.
Suddenly, the clock stopped. I looked up at the wall. The hands were frozen at 1:03. The second hand still.
The silence in the room began to feel wrong. Like a layer of cotton wrapping every sound—the fridge's hum gone, the occasional footsteps in the hallway gone, the traffic on the street below gone.
The whole world was sealed in a vacuum jar. I slowly stood up. The sofa spring creaked, the sound cut off halfway, as if strangled. The living room nightlight was still on, its orange glow pooling on the coffee table. At the edge of the glow, a small puddle had appeared on the floor. Round. About five centimeters across. Sharp edges.
I followed the direction of the puddle. In the darkness beyond the nightlight's reach, by the shoe cabinet at the door, there was a trail of water beads. One after another, evenly spaced, stretching from the doorway to the center of the living room. I stood by the glow, the soles of my feet going cold.
The nearest bead was about thirty centimeters from my toes. As if someone stood right in front of me, and if I looked up, I'd see his face.
I slowly raised my chin. The full-length mirror above the shoe cabinet reflected the nightlight and the coffee table. And a blue figure standing behind me, the hem of the wet raincoat dripping. I didn't turn around. The figure in the mirror didn't move either.
He wore the same dark-blue raincoat from last night, hood pulled low. But from the mirror's angle, I could see the face under the hood. That face was mine. The corner of the mouth crooked, as if smiling. Bluish chin, a sheen of water on the skin.
I clenched my fists, nails digging into my palms. The figure in the mirror tilted its head slightly. A drop of water slid off the raincoat hood, plip, onto the tile, forming another dot.
Then the sound came back. The fridge hummed on, the wall clock ticked a beat.
I blinked. Only I remained in the mirror—white T-shirt, shorts, messy hair, no color in my face. The water stains on the floor were still there. A line of dots from the doorway to the center of the living room, the nearest one thirty centimeters from my toes.
I backed up two steps, my heel hitting the sofa leg, and dropped onto the cushion. The slip still lay on the coffee table, the writing on the back faintly glowing blue under the nightlight. "You saw it." I stared at it for a long time. Then I picked up my phone and messaged the director: "Director, I'll come in to work tomorrow as normal."
After sending it, I flipped the phone face-down on the table and stared at that line until dawn.
Seven a.m. Sunlight leaked through the curtain gap onto the floor. The water stains had dried, leaving only faint gray marks you'd barely notice. I got up from the sofa, washed my face, changed into a clean shirt, and folded the slip into my chest pocket. Before leaving, I stood before the mirror and looked at myself. Pale, dark circles under my eyes, but the corner of my mouth was straight.
I rode to the hospital.
Eight forty-five, I reached the department. The director was in his office drinking tea. He looked up, lifted his chin. "Weren't you on leave? Back already?" "It's fine now. Fixed the window." He nodded without further questions. I changed into my white coat, sat at desk No. 3, turned on the computer, logged in. Today's appointment list popped up on screen. I scrolled down.
Nine-twenty. There was a name. Lin Mo. Department: Emergency Internal Medicine. Attending doctor: blank. The system marked it "Registered, not yet seen." I stared at the name for a few seconds, then clicked details.
Registration time: 2:17 a.m. today, via "self-service machine." The machines in the ER never shut down at night, that row along the wall could print slips. The signature field was blank.
I closed the page, stood up, walked to the end of the corridor. The stairwell door was open, the motion light on. I stepped in, and the light went out.
In the instant before it died, I caught a glimpse of a figure in a raincoat crouched in the corner, at the bend of the stairs, hood hanging low. When the light came back on, it was gone. A small puddle on the floor, round, five centimeters across, sharp edges.
I backed out into the corridor and checked the wall clock. 9:28. The slip in my pocket suddenly burned, right against my chest through the shirt, like someone had jabbed a finger into my skin. I pulled it out. The writing on the back had changed. Below the original "You saw it," another line had appeared.
"This time, don't look back."
I took a deep breath, folded the slip and put it back, turned and walked to my desk, and sat down. At 9:30 sharp, the ER doors opened.
The person who came in wore a dark-blue raincoat, dripping from head to toe, a white registration slip in hand, hood pulled low. He walked toward me. Drip, drip, drip—evenly spaced, each step leaving a frozen dot on the tile, edges sharp as if drawn with a compass.
On the floor in front of my desk, the dots slowly joined into a line, winding from the doorway to my feet. The raincoat man stopped. I felt that smell of mothballs and wet rust flood my nostrils again.
The soft rustle of fabric, the plip of water on the counter, and a faint breath—like it came from my own throat, its rhythm exactly matching mine.
The person across the desk didn't move. Neither did I raise my head.
The time in the corner of the computer screen flicked to 09:31. In the system, the entry "Lin Mo—registered, not seen" changed status, the bar turning into a green checkmark.
Seen. I stared at the checkmark for two seconds, my throat tight. A wet slip had appeared on the desk, edges curled, blue-black handwriting slowly bleeding through the damp thermal paper. I recognized those crooked strokes, and that ending hook.
The knuckles of my pen hand went white. The backing sheet in my chest pocket burned again.
Outside, the typhoon's leftover wind rattled the window frames. A child was crying in the IV area. All the sounds had come back. And I kept my eyes lowered, never once lifting them to look at that face—my face.
The window glass reflected the desk and two figures. All I had to do was raise my eyes a little to see the raincoat man still standing there. Water dripped from his hood. Drip. Drip. Drip.
I didn't look up.
