I need a REALLY scary horror movie to watch?

HAhah I feel the same way. But one of the scariest movies I ever seen was the Exorcist since I believe that there's a devil. But generally I find movies to be really scary if they are actually real or based on a true story. there scary cause that stuff actually happens. I like 1408 that movie made me feel uneasy and a lil jumpy. . LOL Nightmare on Elm st used to scare the crap out of me in the 80's.
