His skin and clothes grinded against the walls of what felt like a dark, narrow tunnel. There was no wind rushing in his ears, just silence and his own grunts. And the tunnel grew more narrow as he fell.

The tunnel closed into his body and he finally stopped, trapped in place. He felt some dust fall onto his face as cold sweat ran down his spine.
"This is okay, this is okay," he repeated to himself, breathing through his nose and trying to stay calm.
