I think I'm possessed by a demon?

I think I am possessed by a weak pive demon. I sleep easily during the day, but can't seem to sleep at night. I love watching people in pain. I love watching people get hurt. I think about killing people a lot. I love the taste of blood. I love watching gory horror movies cus it makes me happy to see people getting torn to pieces. I love jeffrey dahmer for the same reason. most likely possessed by a demon right?
