Poltergeist scared the shit out of me when I was little...that damn clown, and those corpses floating in the pool...omggggg...that is one of the scariest movies I've seen.
Also, The Sixth Sense. That was reeeeally scary when I saw it. I hate when things jump at me. I was also spoiled the ending before I saw it...actually, I asked to have it spoiled. I'm terrible.
MIL spoiled The Sixth Sense for me. I want to say what she said but I don't want to spoil it for anyone who hasn't seen it. Oh well, it's not important, but we were watching it and were about half way through when she came home and ruin my whole experience in one sentence.
And speaking of M. Night (I don't know how to spell his last name). The alien movie he did there was one part that creeped me out pretty bad. When the kids are at the birthday party and the alien walks by and stops and looks right at them. DON'T LOOK AT ME CREEPY KILLER ALIEN!
I know EXACTLY what part you're talking about. Me and a bunch of friends went to see Signs in the theater, and I remember we screamed bloody murder during that part!!
