Generally speaking, most dreams are only interesting to the person having them, and they don't actually make for very good stories to tell others. Given this, it was kind of inevitable that eventually, someone would try to make a film based on a dream, and they would end up creating an incoherent mess.
Francis Ford Coppola is a legendary filmmaker, who has made many films that are true masterpieces. His 2011 film "Twixt" is not one of them. It follows a horror novelist named Hall Baltimore, who arrives in a small town for a book signing. However, after learning of a gruesome murder that just occurred there, Hall decides to stay a while, with the idea that it might help to inspire his next novel. By night, Hall dreams of a colorless, ghostly version of the town, where he encounters a mysterious girl named "V." Hall continues to investigate the murder by day and experience haunting dreams by night, before eventually learning the truth of what's really going on in this sleepy little town.
Speaking on the origins of the film, Coppola says, "[It] grew out of dream I had last year — more of a nightmare ... But as I was having it I realized perhaps it was a gift, as I could make it as a story, perhaps a scary film, I thought even as I was dreaming" (via The New York Times). It's not entirely clear exactly what Coppola was going for with this one, but this is a case where whatever he feeling when he was asleep wasn't something he was able to translate into our waking world of sunlight and logic.
