To continue what Valet Every Wish has said, this is very good with some vivid imagery, but the problem for me is the length. Suddenly the devil appears...

...and the poem ends! We want more! :-)

I think your poem was great dark and sinister loved it but at the end it lost its rythem and it needed more added after the devil appears but other than that great work

A nice attempt. It also reminds me of my childhood, sleeping in a dark and feelings at that time. Try to use ore simple and smaller words..

Very good! :)
