The monster has lived there since I can recall,
So long I often forget to remember him at all.

When he does show up, he never knocks,
But rather climbs into my brain as if he belongs.

He leaves me dark and leaves me weak,
He even takes my memories so that I cannot speak.

In my mind, he is always me, whether he resides under the bed
Or in my sleep, or in my head.

One thing I have never tried,
is to receive him in and let him abide.
