People with type 1 narcolepsy have low levels of hypocretin hi-poe-KREE-tin , also called orexin.

Hypocretin is a chemical in the brain that helps control being awake and when you enter REM sleep. Hypocretin levels are low in people who experience cataplexy.

Exactly what causes the loss of hypocretin-producing cells in the brain isn't known. But experts suspect it's due to an autoimmune reaction. An autoimmune reaction is when the body's immune system destroys its own cells. It's also likely that genetics plays a role in narcolepsy. Research also indicates that in some cases narcolepsy may be linked to exposure to the swine flu H1N1 flu virus.

It also may be linked to a certain form of the H1N1 vaccine. The vaccine was administered in Europe. The typical process of falling asleep begins with a phase called non-rapid eye movement NREM sleep. During this phase, brain waves slow.

After an hour or so of NREM sleep, brain activity changes and REM sleep begins. Most dreaming occurs during REM sleep. In narcolepsy, you may suddenly enter REM sleep without going through NREM sleep.

This can happen both at night and during the day. Cataplexy, sleep paralysis and hallucinations are similar to changes that occur in REM sleep. But in narcolepsy they happen while you're awake or drowsy. Narcolepsy care at Mayo Clinic.
