I also want to see what other people are doing, and whether I can help anyone with their sleep problems.
What is sleep paralysis? Sleep paralysis is a sudden involuntary reaction to a specific visual stimulus which usually is a light in the night. The sensation of paralysis may be brief or may be continuous and may last only a few seconds. There are two major types of sleep paralysis: In a REM (rapid eye movement) sleep paralysis, the individual may fall asleep and wake up again as soon as he or she attempts to go to sleep. This kind of sleep paralysis is common in patients with Alzheimer's disease and other conditions of sleep and is a frequent symptom of narcolepsy, also known as "waking syndrome". There is also a form of REM sleep paralysis that occurs when an individual is fully conscious during the REM phase of sleep and then falls asleep. This type of sleep paralysis may be caused by a medical condition such as catatonia (loss of muscle tone) and may not be an indication of narcolepsy. Most of the time, individuals who have narcolepsy and sleep paralysis don't suffer from them and are simply having one of the more bizarre dreams.
A common symptom of narcolepsy is extreme fatigue, even in the morning.
