Four padded walls ... covered white, shredded.

Locked within the mind, this is my sentence,
strapped down and sedated within, trance like
state, catatonic and useless.

I want out ...

I can't find the key. I thought I'd placed it some
where safe, so this would not happen. Yet, here
I stand, looking stupid in the middle of my mind.

Then I look, only to find that there is no door to
speak of. There are only four walls to stare at,
with a floor and a rather low ceiling, which does
seem to be shrinking.

Maybe it's just me, my imagination.

There is no door, so there is no key.
