Is this a normal fetish?

The other day, I was watching a horror movie with a friend of mine. During a really epic scene in which a dumb blonde bitch just got disemboweled, and her dumb blonde boyfriend looks dejectedly down at her, the bad guy starts slowing walking up to him from behind him. I hadn't noticed at the time, but at the end of the movie, my friend told me I had this odd look on my face; she said my face was red, I was breathing hard, and my eyelids were drooping. This has happens when I watch other horror movies.
Long story short, I have a fear fetish. I like being afraid. It turns me on.
Is that normal?
