I had this dream last year on Christmas Eve and I couldn't sleep really good well enjoy

It was a hard day of school after all of the stress,pain,and gloom I was finally close to home as if I haven't been there for years.I enter my house I felt like something bad was going to happen so I went to my room and did what I would always do when I am alone...cut myself,so I grabbed a knife and I started to cut my cold,dry skin then I saw no blood come out and I knew that wasn't normal so I cut myself deeper and I saw a hand come out of my arm and it started to stab me and I know that it was normal to me but it was my very own secret and I said to the hand."this will be our own secret for us to keep,"then the hand came out of me and it ended up being a siren and it devoured me."secret kept,"she said.
