· Nightmares, which tend to be more common in girls than boys, usually begin in childhood before age 10 and are considered normal unless they significantly interfere with sleep, development, or psychosocial development. They may continue into adulthood where they are often associated with outside stressors, anxiety, or trauma. They may also exist alongside another mental disorder.
· Nightmares are lengthy, elaborate dreams with imagery that evokes fear, anxiety, or sadness. The dreamer may wake up to avoid the perceived danger. Nightmares can be remembered upon awakening and may lead to difficulties returning to sleep or even cause daytime distress.
