LJ Brain Trust: creepy movies?

I want to rent a creepy movie for Halloween.

Note that "creepy" does not equal "gory"; in fact, a movie with little to no blood would be best. I'm thinking of something in the vein of Sixth Sense, The Others, or mmmmmmaybe The Ring. (which was just at the bounds of my tolerance for creepy and might be beyond Laura's.) I'm looking for mindfuck, basically, not serial killer.

Any suggestions?
