That last verse was really creepy. I was lying on my bed.. in the dark, reading it to myself. *shivers* Really good job on this one!..
Just one suggestion..

I think the last verse should be written like this;

Its here,
lurking over my shoulder.
Just waiting for me
to let my guard down,
before it attacks me,
and tears me
and my being apart.

I just thought it read a lot better that way. Up to you!..

Coming from someone who suffers from a condition known as night terrors, this hit home for me..
To much for me as well, lol
But excellent portrayel as always
5/5
*Gem*
