I saw this movie and it freaked me out for weeks. I actually had trouble sleeping for about a week.
a few days after I saw it, my GF went out of town, and sleeping alone was almost hell. I am very surprised the movie had that much affect on me. Movies about killers and monsters and such don't ever get to me. I feel if I ever encounter one, I can fight back, but a ghost? What the heck can you do to fight the ghost?
