Can you recommend any "weird" movies?

This is kind of hard to explain, but I’m looking for movies that are out there, mysterious, weird, and the addition of being kind of creepy is always a plus. Just to show an example, I’ll tell you that two of my favorite movies are “Donnie Darko” and “Memento”.

Are there any movies out there like those two? I love “The Twilight Zone”, “The X Files”, “Outer Limits”, “Unsolved Mysteries”, “Lost”, and others like that. Does anyone have any recommendations?

Any “mindfuck” movies? Or books even?
