I tend to get scared ridiculously easily by scary things in video games. I get scared just facing those blue ogre creatures in Twilight Princess and have to keep pausing When it comes to movies, it's not quite as bad.
I don't really deal much with either. I find most things that try to be "scary" to be utterly boring and predictable. Some of that stuff grosses me out, yes. But it disgusts me much more than it terrifies me.
I'm more scared when people sneak up behind me IRL. And I've found out that the New Jersey Turnpike packs in more horrors than any scary movie or game.
