Yeah I agree with those. Mushishi almost matches exactly my hallucinations during my one experience with magic mushrooms so you might want to check that out too.
Samurai Champloo is also pretty cool, the animation style plus the music makes it kinda cool.
And I will never hesitate to recommend Windy Tales (Fuujin Monogatari). There is some super psychadelic episodes there and the whole concept is very trippy - flying cats and school girls who control the wind.
Yeah, Cat Soup is short and weird, so you might like that.. Um, I agree with a lot of the things said.. FLCL, Excel Saga.. It is my plan to watch dead leaves, and it seems like it'll be weird (and Krelain suggested it so yeah...)
Texhnolyze, that serie is weird, still cool, but in a weird way :p
Paranoia Agent, didnt really like it as much myself, but its fits in what you search.
If you search at the genre "Dementia" at for example : www.anidb.net , I think you would find what you are looking for ;)
you all are forgetting the crazyest tripped out piece of animation ever... HEAVY METAL...
Big breasted chicks wacked out aliens wierd ass trippy shit... a trippy gloing orb... stright up crazyness...thers aliens getting all Feked up off zarfnar.. plus its got the voice of john candy... how can you go wrong? even though its not japanamie its canadime canadian animation son.. its trippy as hell its got good music its animated... and well some people consider avatar anime but its clearly made in america... and you will mostlikely find it in the anime section of your local blockbuster...
I'm gonna have to agree on with Dead Leaves and FLCL being pretty wild.
Dead Leaves is about some amnesiacs who wake up naked and then get sent to prison and have to break out.
FLCL is about an alien named Haruko Haruhara who comes to Earth in search of someone called the Pirate King, but while doing so she helps a boy grow up.
Also, I'd like to personally add Kick Heart. I didn't like it, but its about 11 minutes long and its really weird. Its a love story between a masochistic wrestler and a sadistic wrestler.

A boy is asked by his father to pilot a giant robot and fight against aliens called Angels trying to get to something on Earth. But while doing so, he discovers many secrets about the Angels and the robot he pilots.
