Wow!

I absolutely love this entire poem. I am shocked nobody has taken the time to comment on it.

You pulled me in from the Title and gripped me with the first stanza.

Love the rhyming, I love how much description you gave. From the grimy cell to the detail and metaphors you use to describe the door and the monster which resides.
This is a twisted poem so beautifully written. The darkness and ever magical fantasy it paints are wonderful.

This battle between you and the horror of this door is very emotionally charged.
I relate - I can really take a lot of this poem and process it as my own battles within my head, my life, my heart.
You etched a very telling piece that is alluring - gripping the reader in and honestly, I read it more than once because of the power it has. I nominated it for content, it really is that good. It reminds me of what true nightmares are made out of.
You have true talent!
