A voice in my head

There is a voice in my head
That is not my own.
It whispers sinister secrets to me-
Chatters away with distant noise.

I wish it would just sleep.
A moment of silence,
So I could find a sense of truth
And see myself in this darkness.

It is such a great effort to think
And know that what thoughts
You have are yours and not
Borrowed from hell.

This monster crept up on me
In the recent blackness that
Consumed me.
