What is dream / Khwab?
Dreams/Khwab are the images, thoughts & feelings experienced while sleeping, particularly strongly associated with rapid eye movement sleep. The contents & biological purposes of dreams are not fully understood, though they have been a topic of speculation & interest throughout recorded history. The scientific study of dreams is known as oneirology.
The most usual emotion experienced in dreams is anxiety. Negative emotions are more usual than positive ones. The U.S. ranks the highest amongst industrialized nations for aggression in dreams with 50 percent of U.S. males reporting aggression in dreams, compared to 32 percent for Dutch men.
The Hall data analysis shows that sexual dreams occur no more than 10 percent of the time & are more prevalent in young to mid teens. Another study showed that 8% of men’s & 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.
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 & 65% of males report recurrent dreams.
Content-analysis studies have identified usual reported themes in dreams. These include: situations relating to school, being chased, running slowly in place, sexual experiences, falling, arriving too late, a person now alive being dead, teeth falling out, flying, embarrassing moments, falling in love with random people, failing an examination, not being able to move, not being able to focus vision & car accidents. Twelve percent of people dream only in black & white.
