John Harper, thank you for suggesting Paprika. The movie is bizarre, awesome and creepy. Definitely a mindtrip.

The opening five minutes, with the weird dream montage that switches from Tarzan to Spy Thriller to Personal Life so abruptly, had me hooked.

I think there were also moments that had me deeply unsettled. The hand sinking into the crotch (butterfly scene) unsettled me so much. The sexualization of the dolls in one part was icky. But... I think those icky bits helped reinforce what was going on. I felt deeply disturbed at the possibility of dream crossing. Moreso than The Cell.

I thought it was weird how those icky, disturbing, violent moments were offset by Paprika soaring around on a cloud, happy sunshine and theme music playing in the background. Anime is the only medium that I've ever seen successfully pull off such a "clash". Weird.

Yeah, I think Kon is very good at taking (sometimes squicky) anime tropes (the sexy doll thing especially) and treating them thoughtfully. He uses the medium so well. It's hard to imagine Paprika done any other way.

His Hitchcockian thriller Perfect Blue is also great. It has some uncomfortable moments, too, but they work.

Does it meet my needs for mindtrippy, headfuck movies? (Paprika most assuredly did).

Yep. Not in the over the top, reality-bending way of Paprika, but yeah.
