Human: Generate a detailed description of a spooky cave in the wilderness with luminous fungus. Assistant: 
Coarsely hollowed out sandstone walls, covered in luminous crimson fungus, run from an opening in the foundation stones and disappear southward into a veil of darkness. Water drips through tiny cracks between the blocks, creating a light condensation down the length of the rough passageway. As if in dance, the drops trickle down the stone, sent into motion by the subtle vibrations from a low rumbling sound.
