A dream sequence is a technique used in storytelling, particularly in television and film, to set apart a brief interlude from the main story. The interlude may consist of a flashback, a flashforward, a fantasy, a vision, a dream, or some other element. Commonly, dream sequences appear in many films to shed light on the psychical process of the dreaming character. For instance in Pee-Wee''s Big Adventure, the purpose of Pee Wee''s dreams is to inform the audience of his anxieties and fears after losing his bike. Other times major action takes place in dreams, allowing the filmmaker to explore infinite possibilities, as Michel Gondry demonstrates in The Science of Sleep.
