PSYCHOLOGY OF EMOTIONS

Detailed explanation-1: -Sleep terrors are a disorder of arousal, meaning they occur during N3 sleep, the deepest stage of non-rapid eye movement (NREM) sleep.

Detailed explanation-2: -The cause is unknown but night terrors are often triggered by fever, lack of sleep or periods of emotional tension, stress or conflict. Night terrors are like nightmares, except that nightmares usually occur during rapid eye movement (REM) sleep and are most common in the early morning.

Detailed explanation-3: -While people talk about “night terrors, ‘’ this is not, in fact, a diagnosable condition, according to the Diagnostic and Statistical Manual fifth edition (DSM-V). It contains elements of conditions known as nightmare disorder, REM sleep behavior disorder, and Non-Rapid Eye Movement (NREM) Sleep Arousal Disorder.

Detailed explanation-4: -Sleep happens in several stages. We have dreams-including nightmares-during the rapid eye movement (REM) stage. Night terrors happen during deep non-REM sleep. A night terror is not technically a dream, but more like a sudden reaction of fear that happens during the transition from one sleep stage to another.
