Write a detailed description of a spooky scene inside a cave cavern with water and sand.
assistant
The sand here is unusually dry and loose compared to the rest of the cavern, sparkling with unnatural light. The sand seems extremely deep and is difficult to walk on, but somehow manages to hold the weight enough so that anyone attempting to traverse it doesn't sink any further down than their ankles. To the southeast, the ground dips down slightly and disappears into a cavern of murky water.
