I heard a wasp...

Or, at least, I thought I had. It fluttered below the mattress where I lay, though my partner confessed she could not detect the sound that raised so much curiosity and anxiety within me. I searched for it all abound the room, under objects and down the sides, and though it always sounded so close, it never came into sight.
   The next day I was back at home and that night as I attempted to sleep, again I heard a wasp. Such treachery. And so, I penned this...

Hear that?!
It is the sound of a wasp,
both near and far-
an inevitable threat.
Hear it in your head
and flittering somewhere
under
or inside your bed.
Perhaps it is the sound
of my inevitable end...
Hear that?
Or else...
I'm losing my mind.
