A nightmare is a dream that can cause a strong negative emotional response from the sleeper, typically fear and/or horror. The dream may contain situation(s) of danger, discomfort, or psychological or physical distress. Sufferers are usually woken in a state of distress, and might be unable to go back to sleep for a prolonged period.
Nightmares can have physical causes such as sleeping in an uncomfortable or awkward position, or having a fever; and psychological causes, such as stress or anxiety. Eating before bed, which triggers an increase in the body's metabolism and brain activity, is a potential stimulus for nightmares.
Occasional nightmares are commonplace, but recurrent nightmares can interfere with sleeping patterns and cause insomnia, and may require medical help. A recently proposed treatment consists of imagery rehearsal. This approach appears to reduce the effects of nightmares and other symptoms in acute stress disorder and post-traumatic stress disorder.
Studies of dreams have found that about three quarters of dream content or emotions are negative.
One definition of "nightmare" is a dream which causes one to wake up in the middle of the sleep cycle and experience a negative emotion, such as fear. This type of event occurs on average once per month. They are not common in children under 5, but they are more common in young children (25% experiencing a nightmare at least once per week), most common in adolescents, and less common in adults (dropping in frequency about one- third from age 25 to 55).
Fearfulness in waking life is correlated with the incidence of nightmares.
One frequent cause of nighmares is watching a scarry movie before bed, usually contributing to some of the nightmare that young child and adloescents obtain.
As though a thousand vampires, from the day
Fleeing unseen, oppressed that nightly deep,
The straitening and darkened skies of sleep
Closed on the dreamland dale in which I lay.
Eternal tensions numbed the wings of time
While through unending narrow ways I sought
Awakening; up precipitous gloom I thought
To reach the dawn, far-pinnacled sublime.
Rejected at the closen gates of light
I turned, and down new dreams and shadows fled,
Where beetling shapes of veiled, colossal dread
With Gothic wings enormous arched the night.

The term nightmare refers to very powerful dreams that the sleeper finds disturbing. They usually have either physiological causes, such as a high fever, or psychological ones, such as trauma or stress in the sleeper's life. Nightmares are common, but nightmares that happen very often can cause problems with sleep. They may cause people to get medical help.
Nightmares usually occur in REM sleep.
In earlier times, people thought that such nightmares were really the work of demons. They thought people were having nightmares because an Incubus was sitting on the chest of the sleeper. This can also be seen on the image. Sometimes people also thought magic and demonic possession were involved.
In the 19th century, people made the diet responsible. When Ebenezer Scrooge sees a ghost in A Christmas Carol, by Charles Dickens, he makes "... an undigested bit of beef, a blot of mustard, a crumb of cheese, a fragment of an underdone potato..." responsible for the apparition. Similarly, the Household Cyclopedia (1881) offers the following advice about nightmares:
