That time everyone was puzzled. They became more puzzled after that night.
Next morning Shima asked Himu if he heard knocking on the door. He was puzzled after hearing the question. Sohel came from his room at this time to hear this. He told Shima that she might have heard wrong in her sleep. Shima also thought so.'Who would come knocking on her door in the middle of the night'.
That day after breakfast all six of them went to tour the area. After roaming around the village, they saw a small village market only few minutes away from the village. They sat on a tea stall.
The stall owner asked if they are from the city. After hearing that they are the stall owner told them not to go too far away alone and always lock the door before going to sleep. Also, the same thing as the tour guide. When they wanted to know about the reason the stall owner started to speak.
The stall owner "The person you came with did not tell you anything about this"?
Shima "We have no idea what is going on in this place. We just came here on our vacation. Everyone is telling us not to go out at night or not to open door at night, but nobody is telling us the reason behind this. Can you tell us what is going on in detail?"
The stall owner "No one wants to say anything about this because they are scared to talk about this still, I'll tell you. There is a legend about an entity which come at night and knocks on the door. If you open it then it will take you with it but if you don't open the door then you are safe."
Himu "Why is it"?
The stall owner "Who knows"?
Shima "Please tell us in detail about it".
The stall owner "This thing is called NISHI. Because it comes in deep night (In Bangla language Nishi means night. The reason behind this name is it comes at night). Everyone in this village and the neighbouring villages, people know of it. Many villagers heard the knocking sound. Those who opened the door all died and those did not open the door survived."
Sohel "So people saw this thing"?
The stall owner "Nobody saw that thing. Whoever saw it all died."
"Let me tell you something more. During the night if you hear knocking do not open the door no matter what. When it knocks the door, it knocks three times only. Sometimes it may also call you by your name. It will pretend to be someone you are familiar with, and you may open the door without thinking anything. But as long as you are here keep it in mind, after locking the door at night do not open it until next morning in any situation. Also, another thing, few years ago people from city came here on a vacation. On the first night they heard knocking on their door, they thought they heard wrong and did not open it. This happened to everyone but they did not take it seriously and choose not to tell anyone. Next night when one of them heard the knocking again and opened the door. Do you know what happened to that person? Next day when his companions found he was missing and started searching he was found dead on a pond outside the village. That's why I'm saying you should be on guard at night and get out of here as soon as possible. Also if any of you heard knocking already then you might hear it again until it loses interest on you. Otherwise it's not going to be a good thing for you. Also it can follow you anywhere if it want so if you hear knocking then look for the person at the eastern more side. If you tell anyone about it and say you want to solve this then they will show that person. Or you may say that you want to find the person who knows about otherworldly things."
