Jacobs Ladder - Decent mindfukk, one of the first of the genre I had seen so its foggy trying to remember the details. But it was definitely good enough to watch.
Arlington Road - Great mindfukk, makes you ponder in one direction then throws the whole fukking bookcase at you towards the end. One of the top picks. A man and his family suspect the new neighbors of being terrorists. You wont regret this one.
Source Code - Decent, Jake Gyllenhaal never delivers a horrible performance. Solid execution, yet slightly run of the mill mindfukk by the time it hits. But definitely watchable. Sidenote - Jeffrey Wright can play anything from a bum, to a gangster, to a fukking scientist and not have a problem. shyts wild.
Primer - Very dry, but VERY mindbending psychological thriller somewhat scientifically based on time travel. Very believable and worth a watch if you have time. What would you do if you and your best friend/business partner stumbled onto a time machine?
Interstellar - One of the most far reaching, epic movies I've ever seen. You have to have three hrs at least to take it all in. Touches on almost every emotion known to man, complete with spectacular visuals. Give this another shot, just be in the right mood.
The Thirteenth Floor - Classic, the mindfukk comes fairly early compared to most movies and its truly an action/drama at heart. Its about two guys who are managing a simulation of a world set in the 1920s I believe, they break the rules by inhabiting a persons body within the simulator to find the answers to a crime that spans both worlds.
Memento - Total mindbender here, once you get the gist of how the chronological order is, you'll see the genius behind it all. A man with short term memory loss is on the hunt for his wifes killer, he tattoos important notes on himself so he never forgets what to do.
Twelve Monkeys - Love this one, blends the action and psych thrills just right with a competent storyline that Bruce Willis excels in.
Vanilla Sky -
The Prestige -
Will edit later
Couple more, but those should hold you off for awhile.
