I don't know how to explain this one. It's not a poem in the strictest sense I guess, but... I dunno. I'll let whoever reads decide.

You're there...
But you're not.
You see...
But you don't.
You hear...
But you can't.
It's warm here...
Breathe.
I'm comfortable...
Breathe.
Let me sleep...
Breathe!
Don't wake me up...
Don't die...
