I sit within an empty cave.
   It's empty, that's for sure.
 It's dark, so dark that nothing shines.
   What sound is that? A purr?

I'm in this cave, and not alone,
   but with what I can't say.
 It's in the back where it's jet black --
   a predator? Or prey?

I'm walking now; I don't dare run.
   the ground is all cockeyed
 with stalagmites and stalactites.
   I grope, in need of guide.

And feeling through Stygian space,
   I bust open my head.
 Warm blood, I feel, run down my face.
   I'm squeezed by rising dread.

I hear a squeak, a mouse strolls through;
   then silence is restored.
 If only my mind were so rid
   of its outsized horrors.
