List 'em here along with what they did to you!
1- Aliens (1st movie) . Never in my life will I chase a cat in the dark. Alone. Matter of fact, fuk cats.

2- Critters III: The scene where the kid is sleeping on her bed with one arm hanging out of the bed a few inches from the floor... and they scroll the view down and there's the infant Critter jumping up trying to bite it. I now sleep in a Queen size bed.
3- ALIVE! : Always choose rearmost seat in airplanes. The fact that I met one of the guys that was in that crash makes it even worse.
4- The Excorcist: Kinda silly, but whenevers someone sick I pray they dont start puking all over. Especially on me.
5- NEO GENESIS EVANGELION : Funny, the only anime ever to affect me. The scene where Shinji was drowning inside the EVA cockpit really freaked me out. As a scuba diver that scene flashes a lot in my head. Brrr!
6- The Blob. Always, unconciously, I look at the ceiling of every movie theatre im in. Every 20 minutes.
