Other fictional dream worlds include the Dreamlands of H. P. Lovecraft's Dream Cycle[26] and The Neverending Story's[27] world of Fantasia, which includes places like the Desert of Lost Dreams, the Sea of Possibilities and the Swamps of Sadness. Dreamworlds, shared hallucinations and other alternate realities feature in a number of works by Phillip K. Dick, such as The Three Stigmata of Palmer Eldritch and Ubik. Similar themes were explored by Jorge Luis Borges, for instance in The Circular Ruins.
In popular culture
Modern popular culture often conceives of dreams, like Freud, as expressions of the dreamer's deepest fears and desires.[28] In films such as Spellbound (1945), The Manchurian Candidate (1962), Field of Dreams (1989), and Inception (2010), the protagonists must extract vital clues from surreal dreams.[29]
Most dreams in popular culture are, however, not symbolic, but straightforward and realistic depictions of their dreamer's fears and desires.[29] Dream scenes may be indistinguishable from those set in the dreamer's real world, a narrative device that undermines the dreamer's and the audience's sense of security[29] and allows horror film protagonists, such as those of Carrie (1976), Friday the 13th (1980) or An American Werewolf in London (1981) to be suddenly attacked by dark forces while resting in seemingly safe places.[29] Dreams also play a major role in video games. The Nintendo 3DS game Mario & Luigi: Dream Team follows the adventure of the Mario Bros. traveling through Luigi's dreams.
In speculative fiction, the line between dreams and reality may be blurred even more in the service of the story.[29] Dreams may be psychically invaded or manipulated (Dreamscape, 1984; the Nightmare on Elm Street films, 1984–2010; Inception, 2010) or even come literally true (as in The Lathe of Heaven, 1971). In Ursula K. Le Guin's book, The Lathe of Heaven (1971), the protagonist finds that his "effective" dreams can retroactively change reality. Peter Weir's 1977 Australian film The Last Wave makes a simple and straightforward postulate about the premonitory nature of dreams (from one of his Aboriginal characters) that "... dreams are the shadow of something real". Such stories play to audiences' experiences with their own dreams, which feel as real to them
Freudian view of dreams
In the late 19th century, psychotherapist Sigmund Freud developed a theory that the content of dreams is driven by unconscious wish fulfillment. Freud called dreams the "royal road to the unconscious."[30] He theorized that the content of dreams reflects the dreamer's unconscious mind and specifically that dream content is shaped by unconscious wish fulfillment. He argued that important unconscious desires often relate to early childhood memories and experiences. Freud's theory describes dreams as having both manifest and latent content. Latent content relates to deep unconscious wishes or fantasies while manifest content is superficial and meaningless. Manifest content often masks or obscures latent content.
Freud's early work argued that the vast majority of latent dream content is sexual in nature, but he later shied away from this categorical position. In Beyond the Pleasure Principle he considered how trauma or aggression could influence dream content. He also discussed supernatural origins in Dreams and Occultism, a lecture published in New Introductory Lectures on Psychoanalysis.[31]
