Quizplus · Accepted Answer

Nightmares occur during the REM (Rapid Eye Movement) phase of sleep, which is when most dreaming happens, and they can often be remembered upon waking. Night terrors, on the other hand, occur during NREM (Non-Rapid Eye Movement) sleep, particularly during the deep stages, and are typically not remembered. Night terrors involve intense fear, screaming, or even sleepwalking, but they are not dreams and thus not remembered as narratives or images like nightmares.
