Dreams can link to actual sensations, such as the incorporation of environmental sounds into dreams such as hearing a phone ringing in a dream while it is ringing in reality, or dreaming of urination while wetting the bed. Except in the case of lucid dreaming, people dream without being aware that they are doing so. Some philosophers have concluded that what we think 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 was also discussed in Hinduism; Buddhism makes extensive use of the argument in its writings. It was formally introduced to western philosophy by Descartes in the 17th century in his Meditations on First Philosophy.

There is evidence that certain medical conditions (normally only neurological conditions) can impact dreams. For instance, people with synesthesia have never reported entirely black-and-white dreaming, and often have a difficult time imagining the idea of dreaming in only black and white.

Therapy for recurring nightmares (often associated with posttraumatic stress disorder) can include imagining alternative scenarios that could begin at each step of the dream.

Dreams and psychosis

A number of thinkers have commented on the similarities between the phenomenology of dreams and that of psychosis. Features common to the two states include thought disorder, flattened or inappropriate affect (emotion), and hallucination. Among philosophers, Kant, for example, wrote that ‘the lunatic is a wakeful dreamer’. Schopenhauer said: ‘A dream is a short-lasting psychosis, and a psychosis is a long-lasting dream.’ In the field of psychoanalysis, Freud wrote: ‘A dream then, is a psychosis’, and Jung: ‘Let the dreamer walk about and act like one awakened and we have the clinical picture of dementia praecox.’

McCreery has sought to explain these similarities by reference to the fact, documented by Oswald, that sleep can supervene as a reaction to extreme stress and hyper-arousal. McCreery adduces evidence that psychotics are people with a tendency to hyper-arousal, and suggests that this renders them prone to what Oswald calls ‘microsleeps’ during waking life. He points in particular to the paradoxical finding of Stevens and Darbyshire that patients suffering from catatonia can be roused from their seeming stupor by the administration of sedatives rather than stimulants.

Griffin and Tyrrell go so far as to say that "schizophrenia is waking reality processed through the dreaming brain.

From the 1940s to 1985, Calvin S. Hall collected more than 50,000 dream reports at Western Reserve University. In 1966 Hall and Van De Castle published The Content Analysis of Dreams in which they outlined a coding system to study 1,000 dream reports from college students. It was found that people all over the world dream of mostly the same things. Hall's complete dream reports became publicly available in the mid-1990s by Hall's protégé William Domhoff, allowing further different analysis.

Personal experiences from the last day or week are frequently incorporated into dreams.

Emotions

The most common emotion experienced in dreams is anxiety. Other emotions include pain, abandonment, fear, joy, etc. Negative emotions are much more common than positive ones.

Sexual themes

The Hall data analysis shows that sexual dreams occur no more than 10 percent of the time and are more prevalent in young to mid teens. Another study showed that 8% of men's and women's dreams have sexual content. In some cases, sexual dreams may result in orgasm or nocturnal emission. These are commonly known as wet dreams.

Recurring dreams

While the content of most dreams is dreamt only once, many people experience recurring dreams—that is, the same dream narrative is experienced over different occasions of sleep. Up to 70% of females and 65% of males report recurrent dreams.

Common themes

Content-analysis studies have identified common reported themes in dreams. These include: situations relating to school (adolescents), being chased or attacked, running slowly in place, falling, arriving too late, a person alive in reality dead in the dream, a person who is dead in real life alive in the dream, teeth falling out, flying, future events such as birthdays, anniversaries, etc. (with different scenarios), past events in your life (with different scenarios) embarrassing moments, falling in love with random people, failing an examination, not being able to move or focus vision, car accidents, being accused of a crime you didn't commit, suddenly finding yourself naked, wanting to go to the toilet (usually occurs when you need to in reality), losing your car, not knowing where you are and many more[citation needed].

Color vs. black and white

Twelve percent of people dream only in black and white. Recent research has suggested that those changing results may be linked to the switch from black-and-white film and TV to color media.

[From Wikipedia, the free encyclopedia]

Dreams are a succession of images, thoughts, sounds, or emotions passing through the mind during sleep. The content and purpose of dreams are not fully understood, though they have been a topic of speculation and interest throughout recorded history. The scientific study of dreams is known as oneirology.
