Very nice poem!
I like the concept and the way you described things.
Here are a few of my favourite lines:
"I'll slither to your bedplace
and fill your precious head
with dirty nasty nightmares
and fill your heart with dread
one day you will face me"
and
"And i'm beaming with sin
I have no happy feelings
just pain and suffering within"
--- Can't exactly say why I like them, but they stand out to me ^^
Good write!
5/5
