Honestly, I enjoyed reading you poem.
This really caught me, so dark while reading and picturing out every single line of your piece.

I think it is a hallucination? An auditory and visual hallucination. That keep disturbing in the persona. While reading this..I remember the time when I was in my room and afraid for being alone. Experienced about hallucinating for something that never real. And in reality it was only formed in your own thoughts.

Good read.
Good job!
