Eraserhead!
Only if you want to have a perm mental scar. Something like Jacob's Ladder on acid is unthinkable - it was disturbing enough totally sober
I'll add that a bootleg version of The Dark Knight can look very much like a horror movie when you're on acid lol
with the sound off and listening to some good tunes - they almost always seem to synch up - no matter what the music/movie combo...
