Am I losing my mind or do I just have weird interests?

I think I may be crazy. For all my life I have been interested in things people of my age and gender should not be interested in. I am a 14 year old girl interested in zombies, clic slasher films and gore. But that is not what bothers me. When I look at zombies or Freddy Krueger, I feel , or turned on. I find zombies hot or "cute", and I find Freddy just plain y. I am convinced I am a cannibal because I suck my own blood when I bleed and I actually rip off my skin to stuff my face with.I often imagine myself marrying or kissing Freddy or a zombie and I find it extremely odd. 14 year old girls should be obsessed with makeup, fashion, and jewelery, and be prissy, not love slasher films and zombies and gore. Why am I like this?
