Dream art

"Visions", whether from dreams or intoxication, served as raw material and were taken to represent the artist's highest creative potential.

In the late 19th and early 20th centuries, Symbolism and Expressionism introduced dream imagery into visual art.

Expressionism was also a literary movement, and included the later work of the playwright August Strindberg, who coined the term "dream play" for a style of narrative that did not distinguish between fantasy and reality.

At the same time, discussion of dreams reached a new level of public awareness in the Western world due to the work of Sigmund Freud, who introduced the notion of the subconscious mind as a field of scientific inquiry.

In the collection, The Committee of Sleep, Harvard psychologist Deirdre Barrett identifies modern dream-inspired art such as paintings including Jasper Johns's Flag, much of the work of Jim Dine and Salvador Dalí, novels ranging from Sophie's Choice to works by Anne Rice and Stephen King and films including Robert Altman's Three Women, John Sayles Brother from Another Planet and Ingmar Bergman's Wild Strawberries.
