Not a movie, but I really enjoy the dream sequences in Sopranos. There are often audio cues if not video to make you know it's a dream, but sometimes they slip in totally realistic dreams, like when Tony dreams he discloses to Melfi that he murdered Chris. They quickly cut to him lying in bed with Carm and he asks her if he's been talking in his sleep. I also like the dreams by the ocean on the boardwalk, and the ones when Tony is a passenger in the car. I understand that cars in dreams represent control of making one's way in the world. In most of Tony's dreams he's a passenger.
Ken Russell's film Lisztomania included a series of dream sequences. Also, Carlito's Way ended with Carlito (Al Pacino) hallucinating/dreaming while dying.
Large portion of Vanilla Sky was a dream, while Tom Cruise's character was in cryonic suspension. And I don't know if Jacob's Ladder counts. That was just one big hallucination involving flashbacks and "WTH is going on?" moments.
Ken Russel was the master of the dream/hallucination set piece. Another was The Lair of the White Worm.
favorites are the three dream sequences in A Serious Man (Coen bros.) and the nightmares (and hallucinations) in Shutter Island (Scorsese)
Toto downs Professor Marvel's magic hot dog on the grill. Dorothy gets in front of those suspicious scented candles in the wagon. Suddenly, trees start moving, sky gets black, Dorothy & Toto hightail it out of there, stuff starts swirling around. Toto and Dorothy do indeed go somewhere. I'm keeping an open mind. I would like to know more about those candles.
I love this movie. Seuss disowned it, and the film was radically re-edited after a negative test screening ( 9 songs were dropped). What we got is still wonderfully weird.
That reminds me of the Thomasina book I read as a little kid but I'm not sure if I saw the movie. Nice clip.
As a pasttime I make video mixes of, among other things, dream sequences, so this thread is a goldmine. Thanks, everyone! For me, the most dreamlike dream sequences are in 8 1/2 and Wild Strawberries, as noted (both granddaddies of the form), but also the ones in Still of the Night and The Conversation work on every level. I've got five discs' worth already collected and could go on and on, but the most notable others I'd point out would be Vampyr (hard to tell where that one ends, exactly), Freud (obviously), The Dark Past, The Science of Sleep, Arizona Dream, Hour of the Pig (aka The Advocate), and who could forget Terminator 2. Bonus points for The Last Temptation of Christ for probably the longest non-movie-length dream sequence (honorable mention, Last Night in Soho), ca. 30 minutes! Roger Corman regularly featured dream sequences in his Poe flicks; this was around the time he started therapy, which makes their pedestrian quality all the more disappointing.
I've seen so many movies with dreams in them but one that comes to mind is 1967 Belle de Jour with it's elaborated fantasies. Now that I think of it in most of Bunuel's films is hard to tell what's the dream and what's reality.
