Dream Wikipedia

A daydream is a visionary fantasy, especially one of happy, pleasant thoughts, hopes or ambitions, imagined as coming to pass, and experienced while awake. One study found a positive association between having these dreams and successfully stopping the behavior. Dreams of absent-minded transgression (DAMT) are dreams wherein the dreamer absent-mindedly 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). There is also evidence for continuity between the bizarre aspects of dreaming and waking experience. Unless a dream is particularly vivid and if one wakes during or immediately after it, the content of the dream is typically not remembered. The recollection of dreams is extremely unreliable, though it is a skill that can be trained.

The content and function of dreams have been topics of scientific, philosophical and religious interest throughout recorded history. Humans spend about two hours dreaming per night, and each dream lasts around 5–20 minutes, although the dreamer may perceive the dream as being much longer. Anecdotal reports and formal research studies over the past few decades have established a link between melatonin supplementation and more vivid dreams. Night terrors should not be confused with nightmares, which are bad dreams that cause the feeling of horror or fear. Sufferers usually awaken in a state of distress and may be unable to return to sleep for a prolonged period of time.

The latter definition distinguishes hallucinations from the related phenomena of dreaming, which does not involve wakefulness. Similarly, research scientists, mathematicians and physicists have developed new ideas by daydreaming about their subject areas. 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. There are many different types of daydreams, and there is no consistent definition amongst psychologists. And someday there will be a great awakening when we know that this is all a great dream.

This dreamer, upon becoming lucid, signaled with eye movements; this was detected by the website whereupon the stimulus was sent to the second dreamer, invoking incorporation into that dreamer’s dream. The website tracked when both dreamers were dreaming and sent the stimulus to one of the dreamers where it was incorporated into the dream. In 1975, psychologist Keith Hearne successfully recorded a communication from a dreamer experiencing a lucid dream.

Subjective experience and content

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. In this state the dreamer may often have some degree of control over their own actions within the dream or even the characters and the environment of the dream. In speculative fiction, the line between dreams and reality may be blurred even more in service to the story. Unlike many dream worlds, Carroll’s logic is like that of actual dreams, with transitions and flexible causality.

Modern popular culture often conceives of dreams, as did Freud, as expressions of the dreamer’s deepest fears and desires. Especially preferred by visual artists were the Jacob’s Ladder dream in Genesis and St. Joseph’s dreams in the Gospel according to Matthew. Another experiment gave subjects a fake diary of a student with apparently precognitive dreams. In one experiment, subjects were asked to write down their dreams in a diary.

• 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.
• Because REM sleep is detectable in many species, and because research suggests that all mammals experience REM, linking dreams to REM sleep has led to conjectures that animals dream.
• Results indicated that participants from varying parts of the world demonstrated similarity in their dream content.
• 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.
• Until and even after publication of the Solms 2000 paper that certified the separability of REM sleep and dream phenomena, many studies purporting to uncover the function of dreams have in fact been studying not dreams but measurable REM sleep.
• Yet the stupid believe they are awake, busily and brightly assuming they understand things, calling this man ruler, that one herdsman—how dense!

Hallucination

One theory of déjà vu vegas casino apk download attributes the feeling of having previously seen or experienced something to having dreamed 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. Hypnogogic and hypnopompic dreams, dreamlike states shortly after falling asleep and shortly before awakening, and dreams during stage 2 of NREM-sleep, also occur, but are shorter than REM-dreams. In line with the salience hypothesis, there is considerable evidence that people who have more vivid, intense or unusual dreams show better recall.

Dreams occur mainly in the rapid-eye movement (REM) stage of sleep—when brain activity is high and resembles that of being awake. It is not known where in the brain dreams originate, if there is a single origin for dreams or if multiple regions of the brain are involved, or what the purpose of dreaming is for the body (or brain or mind). Melatonin is a natural hormone secreted by the brain’s pineal gland, inducing nocturnal behaviors in animals and sleep in humans during nighttime. There are numerous examples of people in creative or artistic careers, such as composers, novelists and filmmakers, developing new ideas through daydreaming.

Illusion of reality

In dreams, incomplete material is either removed (suppressed) or deepened and included into memory. From a Darwinian perspective dreams would have to fulfill some kind of biological requirement, provide some benefit for natural selection to take place, or at least have no negative impact on fitness. Ancient Egyptians believed that dreams were the best way to receive divine revelation, and thus they would induce (or “incubate”) dreams.

Lucidity

• 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.
• Dreaming aided survival by replicating these threats and providing the dreamer with practice in dealing with them.
• Freud, whose dream studies focused on interpreting dreams, not explaining how or why humans dream, disputed Robert’s hypothesis and proposed that dreams preserve sleep by representing as fulfilled those wishes that otherwise would awaken the dreamer.
• One theory of déjà vu attributes the feeling of having previously seen or experienced something to having dreamed 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.

After antiquity, the passive hearing of visitation dreams essentially gave way to visualized narratives in which the dreamer becomes a character who actively participates. However, humans dream during non-REM sleep, also, and not all REM awakenings elicit dream reports. Because REM sleep is detectable in many species, and because research suggests that all mammals experience REM, linking dreams to REM sleep has led to conjectures that animals dream.

Illusion of reality

The most famous of these dream stories was Jacob’s dream of a ladder that stretches from Earth to Heaven. The second is the belief of the soul leaving the body and being guided until awakened. They went to sanctuaries and slept on special “dream beds” in hope of receiving advice, comfort, or healing from the gods. Dreams present a running narrative rather than exclusively visual imagery. Denied precision tools and obliged to depend on imaging, much dream research has succumbed to the law of the instrument. Also, fMRI signals are too slow to explain how brains compute in real time.

To be studied, a dream must first be reduced to a verbal report, which is an account of the subject’s memory of the dream, not the subject’s dream experience itself. Framing the dream experience varies across cultures as well as through time. A dream is a succession of images, dynamic scenes and situations, ideas, emotions, and sensations that usually occur involuntarily in the mind during certain stages of sleep. Chemically isolated in 1958, melatonin has been marketed as a sleep aid since the 1990s and is currently sold in the United States as an over-the-counter product requiring no prescription.

Subjective experience and content

More recent studies of dream reports, while providing more detail, continue to cite the Hall study favorably. In 1966, Hall and Robert Van de Castle published The Content Analysis of Dreams, outlining a coding system to study 1,000 dream reports from college students. Preserved writings from early Mediterranean civilizations indicate a relatively abrupt change in subjective dream experience between Bronze Age antiquity and the beginnings of the classical era. It was only in the 13th century that the word dream was used to describe “a series of thoughts, images or emotions occurring during sleep”.

Gudea, the king of the Sumerian city-state of Lagash (reigned c. 2144–2124 BCE), rebuilt the temple of Ningirsu as the result of a dream in which he was told to do so. Etymologists believe that this change was influenced due to the Old Norse draumr, which had the same meaning as the word dream nowadays. Dream interpretation, practiced by the Babylonians in the third millennium BCE and even earlier by the ancient Sumerians, figures prominently in religious texts in several traditions, and has played a lead role in psychotherapy.

The visual nature of dreams is generally highly phantasmagoric; that is, different locations and objects continuously blend into each other. Results indicated that participants from varying parts of the world demonstrated similarity in their dream content. In Old English, the word drēam was used to describe “noise”, “joy”, or “music”, but not related to the sleep-induced brain activity. Therefore, dreaming by non-humans is currently unprovable, as is dreaming by human fetuses and pre-verbal infants. The human dream experience and what to make of it has undergone sizable shifts over the course of history. Most modern dream study focuses on the neurophysiology of dreams and on proposing and testing hypotheses regarding dream function.

Many later graphic artists have depicted dreams, including Japanese woodblock artist Hokusai (1760–1849) and Western European painters Rousseau (1844–1910), Picasso (1881–1973), and Dalí (1904–1989). In the West, artists’ depictions of dreams in Renaissance and Baroque art often were related to Biblical narrative. Graphic artists, writers and filmmakers all have found dreams to offer a rich vein for creative expression. This diary described events from the person’s life, as well as some predictive dreams and some non-predictive dreams. This prevented the selective memory effect, and the dreams no longer seemed accurate about the future. He argued that important unconscious desires often relate to early childhood memories and experiences.
