What is the SCARIEST MOVIE of ALL TIME?

I want a movie that will movie that will make me piss my pants and not be able to sleep for weeks. I don't want a horror/gory movie. I want a freaky movie. Don't tell me a movie that was pretty scary. I want a movie that gave you trouble to sleep for weeks and it was horrifying to be alone in your own house. PREFERABLY A PARANORMAL MOVIE. Those always seem to be freaky. And don't even say the Ring because that wasn't scary at all.
