I've lost perspective on what freaks people out

A Clockwork Orange was fairly depraved, but I didn't find it to be particularly disorientating or especially intellectually challenging. Mind Fuckery could be either exceptionally disturbing, disorientating and difficult to comprehend, or strenuous to mentally digest*. I kind of prefer that later definition, but I like materials that can be described as either.
I can't think of anything that is just disturbing, but not outright horror, y'know, twisted but not just gory and scary. The Ring does some of that, but is pretty settled into the horror genre. Japanese horror comics
definitely do that, but I don't know if they get film adaptations. (Not violent or particularly gory, but do note that I am highlighting it for it's disturbing nature)
As for disorientating and incomprehensible, there's movies with premises that are alien and challenging, although I think they tend to try and make up for mental challenge of the set up with plots that are as straight forward as possible. Inception got talked up for being wild and innovative, but the story was fairly formulaic (aside for the Philip K. Dick style "oh wait, that doesn't actually add up at all" moments).
Eternal Sunshine of the Spotless Mind was a bit more ambitious, and had a lot of fun with it's set up, I think Michel Gondry does that well, but for me, didn't reach 'messes with my head!' status.
For the last category of mindfuckery, I guess there's usually overlap with the other two, but also brings in something extra.
Cat Soup ( or Nekojiru-so) is definitely there. It's a wordless story about adorable anime kittens journeying through the afterlife, and kind of horrifying in some places.
In a similar vein, anime, Paranoia Agent is a t.v. series that gets pretty freaked up, and I've been wanting to see Paprika a bit.
I don't think I can talk about movies that hurt your brain without giving mention to After Last Season. It is an independent film made by an unknown director who clearly does not understand what a movie is. I don't know if it's still possible to get a copy though.
*I'm feeling like there should be a better word for this than confusing. Maybe I'm blanking on a term that means "you thought everything was one way, but then something happens that reveals that everything is actually another way, and you have to go back and re-evaluate your interpretation of all past events".
