Question

Quizplus · Accepted Answer

Nightmares are frightening and anxiety-arousing dreams that occur primarily during the REM stage of sleep. Unlike night terrors, which typically occur during non-REM sleep and involve behaviors such as screaming and sleepwalking, nightmares primarily involve vivid and often disturbing dream content that causes the sleeper to feel fear, anxiety, or other negative emotions. Nightmares can cause sudden awakening from sleep and difficulty returning to sleep, and they can be caused by a variety of factors, including stress, anxiety, trauma, and sleep disorders.
