#2 Nightmare on Elm Street -- The ending is so creepy.
#3 The Blair Witch Project -- I don't think I will ever view camping in the same way again. My DH proposed to me the night we went to see this and that night I was alternating between being so happy and then terrified all night.
#4 The Leprechaun -- I have always been petrified of leprechauns and this movie just proved me right!
UGHH! The Exorcist definitely!! And Amityville Horror. I have a big problem with the ones based on true stories. I've managed to stay away from the Omen, much to my boyfriend's disappointment! Anyone seen Burnt Offerings? Clearly not as horrific as the others, but certainly creepy...
OOH! Forgot Pet Cemetary! Don't know what's worse, the part with the wife's sister yelling at her in bed or the undead Gage at the end!!! Saw it 10 years ago and haven't seen it since!!
