Using diction, create a scary scene (4-5 sentences)

As the man walked through a dark narrow hallway he smelled something like death. Although, he kept walking grasping and touching the wall he sometimes felt a strange sickening water substance dripping as he dragged his fingers across the wall. At that very moment he heard loud crunching noises at the end of the narrow hallway similar to cracked bones. Once he reached the end of the hallway he turned right and fell to the ground as his eyes lingered on such a figure to horrified to speak his worst nightmare had come to life.
That might have been a tad bit gruesome but just wright something along those lines if not just use what I gave I really hope this helps :)
