Write a short description of a spooky scene inside of a cave with a ceiling and lichen.

The air here is strangely dry and chill, with a flat, stale odor. The dark stone floor of the cavern is swept clear of rocks and debris, its uneven surface shining wetly. High above, phosphorescent lichen casts forth a ruddy red-brown glow, arcing in rough spirals across a ceiling otherwise lost in darkness.
