As quoted in Rolling Stone no. 421 (1984)
Context: Talking about dreams is like talking about movies, since the cinema uses the language of dreams; years can pass in a second and you can hop from one place to another. It’s a language made of image. And in the real cinema, every object and every light means something, as in a dream.
