Question

Quizplus · Accepted Answer

Nightmares are dreams that are particularly frightening and can cause the sleeper to wake up feeling scared or upset. This type of dream occurs during REM (rapid eye movement) sleep, which is a stage of sleep when the brain is highly active and most vivid dreams occur. Nightmares are different from night terrors in that the sleeper usually remembers the content of the dream and can describe it upon waking.
