Shutter Island/Nightmare Fuel


 * The whole movie is disturbing. Especially during Teddy's first nightmare,.
 * The guy who  with half his head blown off? Or the many piles of corpses that overflowed from the trains and froze together? Look carefully, and you can see one with a ribcage poking out.
 * The lake scene. It starts so placid, so peaceful and then in a flash the viewer is punched in a face with a gust of the most mind-freezing and dehumanizing insanity, as
 * "Baby, why are you all wet?"
 * The images at Dachau, including the guard who tried to kill himself and failed. What's even more nightmarish is that the horrific images are based on real-life events and actually did drive a squad of soldiers to execute the guards just as we see in the film.
