Enter the Void (2009)

After death, Alex watches over his sister, does he come back? Slow, thrilling and intense all at once + epileptic warning! I'm in love with the way it was done, every frame was absolutely beautiful; seeing things from his blinking eyes while he was tripping, then hovering over the aftermath, the pulsing lights and being apart of his mind.

P.S. You've got to be pretty patient and sober to enjoy this one if you haven't seen it.
