[citation needed] Other times major action takes place in dreams, allowing the filmmaker to explore infinite possibilities, as Michel Gondry demonstrates in The Science of Sleep.

These resonances can reveal a character's subjective observations or desires without breaking away from the objective viewpoint of the narrator, camera, or director with which some theorists, such as Christian Metz, believe the viewer identifies.

Audio or visual elements, such as distinctive music or coloration, are frequently used to signify the beginning and end of a dream sequence in film.

Because it has been done in many occasions to resolve a storyline that seemed out of place or unexpected, it is often considered weak storytelling; a particularly referenced example of this is the TV show Dallas in which the entirety of season 9 was revealed in fact to have been a dream.

For example, entire sequences of the Family Guy two-part episode "Stewie Kills Lois" and "Lois Kills Stewie" are revealed to have taken place within a virtual reality simulation, upon which a character asks whether a potential viewer could be angry that they have effectively watched a dream sequence, but this technique can also be effective and its use lauded when the status of dream or reality is left more ambiguous as it was in The Wizard of Oz.
