Question

Quizplus · Accepted Answer

Narcolepsy is a sleep disorder characterized by sudden and uncontrollable episodes of falling asleep during normal waking hours. These episodes can be accompanied by vivid dreams or hallucinations, such as Sarah experiences. Narcolepsy can also cause sleep paralysis and cataplexy, which are temporary muscle weakness and loss of muscle control during emotional arousal. Sleep apnea is a breathing-related sleep disorder, hypersomnia is excessive daytime sleepiness without sudden sleep attacks, and schizophrenia involves a range of cognitive, emotional, and behavioral symptoms unrelated to sleep.
