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. Another NREM disorder is sleepwalking, which can occur together with sleep terrors. Various factors can contribute to sleep terrors, such as: Sleep deprivation and extreme tiredness.

Detailed explanation-2: -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.

Detailed explanation-3: -Night terror, also called sleep terror, is a sleep disorder causing feelings of panic or dread and typically occurring during the first hours of stage 3–4 non-rapid eye movement (NREM) sleep and lasting for 1 to 10 minutes. It can last longer, especially in children.

Detailed explanation-4: -Whilst nightmares occur during REM (dream) sleep, night terrors occur during NREM (usually stage 3) sleep.

Detailed explanation-5: -Night terrors are like nightmares, except that nightmares usually occur during rapid eye movement (REM) sleep and are most common in the early morning. Night terrors usually happen in the first half of the night.
