The Exorcist was the only movie to ever really traumatize me. Oh & Pet Sematary is a close second. I was a kid, & Pascow just terrified me. I didn't realize at the time he was a good ghost. I just knew he was flippin scary. When I joined the volleyball team at school, I was annoyed because our uniform shorts were the same color of red as the shorts Pascow had on in the movie. Every time I got dressed for a game I would think about him. I was a weird kid.
Pros: Horror movies keep me out of prison. How so? Sometimes when people upset me I'll think, wow I just want to stab you in the face so badly right now. But I don't! I go home & watch a good slasher flick & it's very cathartic for me.
Cons: I miss out on the prison food I hear so much about.
