Oneiric

In a film theory context, the term oneiric (which means "pertaining to dream") refers to the depiction of dream-like states in films, or to the use of the metaphor of a dream or the dream-state to analyze a film. The connection between dreams and films has been long established; "The dream factory" “...has become a household expression for the film industry”. The dream metaphor for film viewing is “one of the most persistent metaphors in both classical and modern film theory”, and it is used by film theorists using Freudian, non-Freudian, and semiotic analytical frameworks.

Oneirology

Oneirology is the scientific study of dreams. The term comes from the Greek oneiros which means dream. A person that studies oneirology is called an oneirologist.
