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: -Night Terror: Disorder characterized by high arousal and an appearance of being terrified. Unlike nightmares, these occur during stage 4 sleep and are typically not remembered.

Detailed explanation-3: -Disorders of Arousal (DOA) are NREM parasomnias characterized by partial awakening from deep sleep in which the subjects are partially or totally unconscious, with inappropriate or absent responsiveness to the efforts of others to intervene or redirect them.

Detailed explanation-4: -Arousal disorders are common in children. Arousal does not mean that the child wakes-up. The “arousal” is a partial arousal usually from “deep” sleep also called “slow wave sleep”. Most commonly the child transitions from deep sleep to a mixture of very light sleep and/or partial wakefulness.

Detailed explanation-5: -Nightmare disorder is characterized by recurrent episodes of awakenings from sleep with recall of intensely disturbing dreams, usually accompanied by dysphoric emotions such as fear, anxiety, or anger, and with full alertness on awakening and immediate and clear recall.
