Narcolepsy is a chronic sleep disorder characterized by excessive daytime sleepiness, sudden urges to sleep, sleep paralysis, and hypnagogic hallucinations.

To determine whether you have narcolepsy, it's best to consult with a qualified healthcare professional for a proper evaluation, which may include a comprehensive medical history, a physical examination, and sleep studies.<|im_end|>
