Human: Please generate a spooky scene inside of a cave with a crack in the wall and a stream of water. Assistant: 
The muted gurgle of running water is an odd intrusion into the quietude of the cavern. A weak flow of water emerges from a small crack high up on the western cavern wall and cascades down over the stone to collect in a small rivulet that runs off to the east. The stream presents no barrier to passage, being only a foot or two wide, and it is only the shallow stone channel, etched into the floor of the cavern by the flow of water over uncounted years, that keeps it from simply spreading out.
