Quick Summary

A night terror, also known as a sleep terror, is a sudden awakening during slow-wave sleep, often accompanied by a shrill cry. Individuals experiencing a night terror appear dazed and terrified but typically do not remember the episode upon waking. These episodes are more common in children and usually occur during non-REM sleep, distinguishing them from nightmares which happen during REM sleep and are remembered. Nightmares are disturbing dreams that cause emotional distress, leading to awakening, while night terrors involve partial awakening with vocalizations and autonomic symptoms like sweating and rapid heart rate. Night terrors are generally forgotten and are considered a type of parasomnia, a sleep disorder.123
