Stuff coming out of holes does make me throw up. I remember seeing baby frogs coming out of their mother's backs.... that's traumatizing. Car crashes are scary.
I have this one specific fear where I hate when women I find attractive get killed out of nowhere. Specifically calm, quiet women who BARELY say a word in movies (if they have glasses, I'll probably freak out more). I jump when they get the most brutal deaths. I guess GTA V (where the lawyer lady accidentally gets herself sliced up in the jet engine, turning into a red cloud) and Akira (Tetsuo's girlfriend being popped like a pimple) messed me up as a kid. Boondocks even had that scene where Luna blew herself up in the car... although I'm starting to detect a pattern with these characters used for the writer to say stuff like "hang around with dangerous men and you'll suffer an equally ugly fate no matter who you are".
Also.... woodchippers... and this fear where tall people accidentally get their heads chopped off by helicopters. And jet engines. Anything with spinning blades is a no-go.
I was going to say demons, but I actually think I'd place that in the rational fear department because with stuff you don't understand, you gotta be on your toes with that kinda stuff. :T
Ghosts I don't find scary though.
