I have such dark fantasies, is that normal?

I have such dark fantasies about being hurt and degraded, is that normal? Should I be thinking these thoughts every night? I dream about men coming to my house when I’m asleep, they break in to my house and force me to do all sorts of degrading things before they kill me. They make me choke on their cocks and they fuck my every hole. They beat me and break my bones and choke me unconscious, sometimes they force huge objects like bottles or a baseball bat in my ass until I scream but still  I wake up every time with my panties soaking wet! I guess I must be a sick person because of this, it can’t be normal! I’m obsessed with the thought of making this all real, I need a man to come and use me, hurt me, make me a nasty whore!
