These are types of parasomnias, which are abnormal behaviors or events that happen during sleep or when transitioning from sleep to wakefulness. These disorders are a result of the brain being partially awake while other parts are still asleep, often occurring during the deep NREM (non-rapid eye movement) sleep stages, particularly in the first half of the night. While common in children, they are usually harmless and resolve on their own, though safety measures are recommended to prevent injury, and medical consultation may be needed if episodes are frequent or severe.
Symptoms include getting out of bed, performing complex actions with eyes open, appearing unresponsive or confused if awakened, and having little to no memory of the event. Sleep terror symptoms involve waking with sudden, intense fear, screaming or crying, sweating, a racing pulse, and thrashing. Both occur during deep non-REM sleep and can lead to safety concerns or disrupted sleep if they happen frequently.
