Seems pretty self-explanatory.

Most David Lynch films

Tetsuo

Fear and Loathing Las Vegas

Vistior Q

Gozu (well, most Takashi Miike films)

Anything by Greg Araki, "Dead Man" and "The Wall". OH, and "Wizards" was pretty trippy, too. (No, not the friggin Fred Savage movie, the animated movie.)

it is the oddest film ever with an even odder trailer... oh 'The Trip' is quite trippy.. if anyone has any idea of what Gozu is actually about please tell me i've watched the DVD about 10 times now and only have faint ideas...

How about the live action version of Alice in Wonderland...anyone know the one I mean? The one with the people in an animal suits, running around.

Also, Naked Lunch by David Cronenberg, although it was just weird for weird's sake mostly.

I adore these films...I love films that kick the shit outta you and make you feel something.

Rubber Johnny by Chris Cunningham.

Oh I really wanna see this. The front cover alone is feckin trippy.

Fire: Walk With Me by David Lynch.

Greatest film I've ever seen.

Suspiria is pretty bizarre. Dario Argento directed horror flick from the 70's.

Dario Argento movies can be very trippy, his cinematography is amazing.

Something a got recently on DVD but that I haven't quite my head round is Jacob's Ladder. Very surreal horror/thriller thing with Tim Robbins.

The title of most psychedelic film ever still goes to: 2001: A Space Odyssey.
