Let's make a list of movies, /x/. Not scary movies, not even paranormal movies really. What I'm looking for are those specific movies that make you stop and think "what the fuck am I watching?". Please, if you know any like this, share! Good, weird movies. I want a movie that makes you (at least once or twice) say "Holy shit!". Any help appreciated.

Pic related, not the best example but Brain Damage is a must see, a great film.
