Further information: Dream world (plot device)
Dream frames were frequently used in medieval allegory to justify the narrative; The Book of the Duchess[24] and The Vision Concerning Piers Plowman[25] are two such dream visions. Even before them, in antiquity, the same device had been used by Cicero and Lucian of Samosata.

They have also featured in fantasy and speculative fiction since the 19th century. One of the best-known dream worlds is Wonderland from Lewis Carroll's Alice's Adventures in Wonderland, as well as Looking-Glass Land from its sequel, Through the Looking-Glass. Unlike many dream worlds, Carroll's logic is like that of actual dreams, with transitions and flexible causality.
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]
