Grim and Surreal Shorts

I find that the most surreal and experimental films tend to carry some sense of dread, whether the storyline makes sense or not. Good horror can often go hand-in-hand with experimental cinema. It makes sense, when you think about it. You can't really scare the same audience with the same trick twice. The following are a few classic shorts in the surreal genre I think every film buff (and especially horror fan) needs to watch at least once...if not dozens of times.
