DREAM

Dreams are successions of images, ideas, emotions, and sensations that occur involuntarily in the mind during certain stages of sleep.

Ancient history

The Dreaming is a common term within the animist creation narrative of indigenous Australians for a personal, or group, creation and for what may be understood as the "timeless time" of formative creation and perpetual creating.[8]
The Sumerians in Mesopotamia left evidence of dreams dating back to 3100 BC. According to these early recorded stories, gods and kings, like the 7th century BC scholar-king Assurbanipal, paid close attention to dreams. In his archive of clay tablets, some amounts of the story of the legendary king Gilgamesh were found.[9]
The Mesopotamians believed that the soul, or some part of it, moves out from the body of the sleeping person and actually visits the places and persons the dreamer sees in their sleep. Sometimes the god of dreams is said to carry the dreamer.[10] Babylonians and Assyrians divided dreams into "good," which were sent by the gods, and "bad," sent by demons - They also believed that their dreams were omens and prophecies.[11]
In ancient Egypt, as far back as 2000 BC, the Egyptians wrote down their dreams on papyrus. People with vivid and significant dreams were thought blessed and were considered special.[12] Ancient Egyptians believed that dreams were like oracles, bringing messages from the gods. They thought that the best way to receive divine revelation was through dreaming and thus they would induce (or "incubate") dreams. Egyptians would go to sanctuaries and sleep on special "dream beds" in hope of receiving advice, comfort, or healing from the gods.[13]

Classical history

In Chinese history, people wrote of two vital aspects of the soul of which one is freed from the body during slumber to journey a dream realm, while the other remained in the body,[14] although this belief and dream interpretation had been questioned since early times, such as by the philosopher Wang Chong (27-97).[14] The Indian text Upanishads, written between 900 and 500 BC, emphasize two meanings on dreams. The first says that dreams are merely expressions of inner desires. The second is the belief of the soul leaving the body and being guided until awakened.
The Greeks shared their beliefs with the Egyptians on how to interpret good and bad dreams, and the idea of incubating dreams. Morpheus, the Greek god of dreams also sent warnings and prophecies to those who slept at shrines and temples. The earliest Greek beliefs of dreams were that their gods physically visited the dreamers, where they entered through a keyhole, and exiting the same way after the divine message was given.
Antiphon wrote the first known Greek book on dreams in the 5th century BC. In that century, other cultures influenced Greeks to develop the belief that souls left the sleeping body.[15] Hippocrates (469-399 BC) had a simple dream theory: during the day, the soul receives images; during the night, it produces images. Greek philosopher, Aristotle (384-322 BC) believed dreams caused physiological activity. He thought dreams could analyze illness and predict diseases. Marcus Tullius Cicero, for his part, believed that all dreams are produced by thoughts and conversations a dreamer had during the preceding days.[16]

In Abrahamic religions

In Judaism, dreams are considered part of the experience of the world that can be interpreted and from which lessons can be garnered. It is discussed in the Talmud, Tractate Berachot 55-60.
The ancient Hebrews connected their dreams heavily with their religion, though the Hebrews were monotheistic and believed that dreams were the voice of one god alone. Hebrews also differentiated between good dreams (from God) and bad dreams (from evil spirits). The Hebrews, like many other ancient cultures, incubated dreams in order to receive divine revelation. For example, the Hebrew prophet Samuel, would "lie down and sleep in the temple at Shiloh before the Ark and receive the word of the Lord." Most of the dreams in the Bible are in the Book of Genesis.[17]
Christians mostly shared their beliefs with the Hebrews and thought that dreams were of the supernatural element because the Old Testament had frequent stories of dreams with divine inspiration. The most famous of these dream stories was Jacob's dream of a ladder that stretched from Earth to Heaven. Many Christians preach that God can speak to his people through their dreams.
Iain R. Edgar has researched the role of dreams in Islam.[18] He has argued that dreams play an important role in the history of Islam and the lives of Muslims. Dream interpretation, is the only way that Muslims can receive revelations from God after the death of the last Prophet Mohammed.[19]

Dreams and philosophical realism

Some philosophers have concluded that what we think of as the "real world" could be or is an illusion (an idea known as the skeptical hypothesis about ontology).
The first recorded mention of the idea was by Zhuangzi, and it is also discussed in Hinduism, which makes extensive use of the argument in its writings.[20] It was formally introduced to Western philosophy by Descartes in the 17th century in his Meditations on First Philosophy. Stimulus, usually an auditory one, becomes a part of a dream, eventually then awakening the dreamer.

Postclassical and medieval history

Some Indigenous American tribes and Mexican civilizations believe that dreams are a way of visiting and having contact with their ancestors.[21] Some Native American tribes used vision quests as a rite of passage, fasting and praying until an anticipated guiding dream was received, to be shared with the rest of the tribe upon their return.[22][23]
The Middle Ages brought a harsh interpretation of dreams. They were seen as evil, and the images as temptations from the devil. Many believed that during sleep, the devil could fill the human mind with corrupting and harmful thoughts. Martin Luther, founder of Protestantism, believed dreams were the work of the Devil. However, Catholics such as St. Augustine and St. Jerome claimed that the direction of their life were heavily influenced by their dreams.

In art

Dreams and dark imaginings are the theme of Goya's etching The Sleep of Reason Produces Monsters. There is a painting by Salvador Dalí that depicts this concept, titled Dream Caused by the Flight of a Bee around a Pomegranate a Second Before Awakening (1944). Rousseau's last painting was The Dream. Le Rêve ("The Dream") is a 1932 painting by Pablo Picasso.

In literature

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 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. 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.
Most dreams in popular culture are, however, not symbolic, but straightforward and realistic depictions of their dreamer's fears and desires. 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 and allows horror film protagonists, such as those of Carrie (1976), Friday the 13th (1980 film) (1980) or An American Werewolf in London (1981) to be suddenly attacked by dark forces while resting in seemingly safe places. 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.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.



Dreams of absent-minded transgression

Dreams of absent-minded transgression (DAMT) are dreams wherein the dreamer absentmindedly performs an action that he or she has been trying to stop (one classic example is of a quitting smoker having dreams of lighting a cigarette). Subjects who have had DAMT have reported waking with intense feelings of guilt. One study found a positive association between having these dreams and successfully stopping the behavior.[101]

Recalling dreams

The recall of dreams is extremely unreliable, though it is a skill that can be trained. Dreams can usually be recalled if a person is awakened while dreaming.[90] Women tend to have more frequent dream recall than men.[90] Dreams that are difficult to recall may be characterized by relatively little affect, and factors such as salience, arousal, and interference play a role in dream recall. Often, a dream may be recalled upon viewing or hearing a random trigger or stimulus. The salience hypothesis proposes that dream content that is salient, that is, novel, intense, or unusual, is more easily remembered. There is considerable evidence that vivid, intense, or unusual dream content is more frequently recalled.[102] A dream journal can be used to assist dream recall, for personal interest or psychotherapy purposes.
For some people, sensations from the previous night's dreams are sometimes spontaneously experienced in falling asleep. However they are usually too slight and fleeting to allow dream recall. At least 95% of all dreams are not remembered. Certain brain chemicals necessary for converting short-term memories into long-term ones are suppressed during REM sleep. Unless a dream is particularly vivid and if one wakes during or immediately after it, the content of the dream is not remembered.[103]

Individual differences

In line with the salience hypothesis, there is considerable evidence that people who have more vivid, intense or unusual dreams show better recall. There is evidence that continuity of consciousness is related to recall. Specifically, people who have vivid and unusual experiences during the day tend to have more memorable dream content and hence better dream recall. People who score high on measures of personality traits associated with creativity, imagination, and fantasy, such as openness to experience, daydreaming, fantasy proneness, absorption, and hypnotic susceptibility, tend to show more frequent dream recall.[102] There is also evidence for continuity between the bizarre aspects of dreaming and waking experience. That is, people who report more bizarre experiences during the day, such as people high in schizotypy (psychosis proneness) have more frequent dream recall and also report more frequent nightmares.[102]

Déjà vu

One theory of déjà vu attributes the feeling of having previously seen or experienced something to having dreamt about a similar situation or place, and forgetting about it until one seems to be mysteriously reminded of the situation or the place while awake.[104]

Sleepwalking

Sleepwalking was once thought of as "acting out a dream", but that theory has fallen out of favor.[citation needed]

Daydreaming

A daydream is a visionary fantasy, especially one of happy, pleasant thoughts, hopes or ambitions, imagined as coming to pass, and experienced while awake.[105] There are many different types of daydreams, and there is no consistent definition amongst psychologists.[105] The general public also uses the term for a broad variety of experiences. Research by Harvard psychologist Deirdre Barrett has found that people who experience vivid dream-like mental images reserve the word for these, whereas many other people refer to milder imagery, realistic future planning, review of past memories or just "spacing out"—i.e. one's mind going relatively blank—when they talk about "daydreaming."[106]
While daydreaming has long been derided as a lazy, non-productive pastime, it is now commonly acknowledged that daydreaming can be constructive in some contexts.[107] There are numerous examples of people in creative or artistic careers, such as composers, novelists and filmmakers, developing new ideas through daydreaming. Similarly, research scientists, mathematicians and physicists have developed new ideas by daydreaming about their subject areas.

Hallucination

A hallucination, in the broadest sense of the word, is a perception in the absence of a stimulus. In a stricter sense, hallucinations are perceptions in a conscious and awake state, in the absence of external stimuli, and have qualities of real perception, in that they are vivid, substantial, and located in external objective space. The latter definition distinguishes hallucinations from the related phenomena of dreaming, which does not involve wakefulness.

Nightmares

A nightmare is an unpleasant dream that can cause a strong negative emotional response from the mind, typically fear and/or horror, but also despair, anxiety and great sadness. The dream may contain situations of danger, discomfort, psychological or physical terror. Sufferers usually awaken in a state of distress and may be unable to return to sleep for a prolonged period of time.[108]

Night terrors

A night terror, also known as a sleep terror or pavor nocturnus, is a parasomnia disorder that predominantly affects children, causing feelings of terror or dread. Night terrors should not be confused with nightmares, which are bad dreams that cause the feeling of horror or fear.
