I just wrote this off the top of my head just now, thinking about a weird thing that happened to me a couple of days ago. It's a bit strange, and I don't think it's very good, but I was in a sort of poetic mood, and this is just what came out.

Paranoia
It's under my bed.
It's in my closet.
It's everywhere.
I can't see it;
I can't hear it.
But it's there;
Oh, it's there.
I hear a noise from across the room.
I sink further into this corner of mine.
I dare not close my eyes.
I can't move a muscle, frozen with fear.
It'll get me;
Oh, it'll get me.
My breathing becomes uneven as my fear rises.
My throat's closing; there's no air.
I shiver at the breeze coming from nowhere.
I'm beginning to panic with dread.
If I don't move, will it think I'm gone?
No, it knows I'm here;
Oh, no, it knows I'm here.
I can't take it anymore!
I force myself to reach out and grab the knife.
If I don't do it, it'll get me.
I raise the knife with shaking hands.
I take my own life.
No, it can't get me now;
Oh, no, it can't get me now.
