Say Hello to Pazuzu
played by a woman... so all you guys that are afraid of this image now know.
As for me the creepiest movie ever was Wolfen, saw it when I was 7 scared me so bad I had night terrors about it. I had such bad night terrors as a kid I was really limited on what I could watch. I remeber my mom telling me I had a night terror when I was 4 or 5 that was so bad it scared both her and my dad. Aparently I walked into their room while I was sleeping and screamed this blood curtling. The both jumped outta bed and when I saw them i began to shake interror so bad they thought i would die of fear. To this day I have no clue what I dreamt that night.
I will tell you I almost always have sore knucles and toes cause i can get so violent in my nightmares/terros that I will repeated punch or kick a wall (whatever is attacking me or I am attacking).
As far as recent movies go. The Japanese version of The Grudge as well as the American version. The woman that gets sucked into her bed. That scene really freaked me out. The other would be Hellraiser, I still have trouble going into a attic alone.
EDIT- BTW I love horror movies and about 47% of my dvd collection consists of it.
