PSYCHOLOGY OF EMOTIONS

Detailed explanation-1: -Narcolepsy is a disorder of rapid onset rapid eye movement (REM) sleep characterized by excessive daytime sleepiness (EDS), frequent uncontrollable sleep attacks as well as sleep fragmentation and can be associated with cataplexy, sleep paralysis, and hypnagogic hallucinations.

Detailed explanation-2: -Sleep attacks, where you fall asleep suddenly and without warning, are also common in people with narcolepsy. They may happen at any time. The length of time a sleep attack lasts will vary from person to person.

Detailed explanation-3: -What Causes a Sleep Attack? Hypocretin, also called orexin, is a brain chemical that controls when you’re awake and when you’re in rapid eye movement (REM) sleep. People with narcolepsy often don’t have as many brain cells that produce hypocretin, but researchers don’t fully understand why.
