Nightmares

Definition:

A nightmare is a dream occurring during rapid eye movement (REM) sleep that brings out feelings of strong, inescapable fear, terror, distress, or extreme anxiety . They typically occur in the latter part of the night and usually awaken the sleeper, who is able to recall the content of the dream. See also night terror ; sleep disorders .

Alternative Names:

Dreams - bad; Bad dreams

Considerations:

Nightmares tend to be more common among children and decrease in frequency toward adulthood. About 50% of adults experience occasional nightmares, women more often than men.

Eating just prior to going to bed, which raises the body's metabolism and brain activity, may cause nightmares to occur more often. Adults who experience repeated nightmares that become a significant problem should seek help.

Common Causes:

anxiety or stress are the most common cause: a major life event precedes the onset of nightmares in 60% of cases
illness with a fever
death of a loved one (bereavement)
adverse reaction to or side effect of a drug
recent withdrawal from a drug such as sleeping pills
effect of alcohol or excessive alcohol consumption
abrupt alcohol withdrawal
breathing disorder in sleep (sleep apnea)
sleep disorders (narcolepsy, sleep terror disorder)
