I have seen almost every good horror flick known to man... Nothing really scares me anymore!! I want something to make me scream, jump, and give me nightmares!! I am hoping someone has a few suggestions... ANYONE?

The Conjuring. The Blair Witch Project. The Orphanage. Paranormal Activities. Inside. Insidious. The Brood. House of Wax. The Omen. Kill List. The Descent. The Tale of Two Sisters. The Strangers. Rosemary's Baby. Black Christmas. Sinister. Women in Black. VHS. The Amityville Horror. Final Destinations. Hills Have Eyes. The Devil's Rejects. Hostel. Hitcher. If none of thoughs pop at u, then you are invincible. ;)

Try the conjuring or insidious

Signs, or Don't Be Afraid Of The Dark (the remake). Two of the very few movies that can actually scare me so hopefully they'll scare you.

Try ring 1 and 2, evil dead 1 and 2, insidious and also The woman in black are really horrifying.
