Sleep paralysis is a common condition characterized by transient partial or total paralysis of skeletal muscles and areflexia that occurs upon awakening from sleep or less often while falling asleep. Stimuli such as touch or sound may terminate the episode, which usually has a duration of seconds to minutes. This condition may occur in normal subjects or be associated with narcolepsy, cataplexy, and hypnagogic hallucinations. The pathophysiology of this condition is closely related to the normal hypotonia that occur during REM sleep. When considered to be a disease, isolated sleep paralysis is classified as MeSH D020188.The paralysis can last from several seconds to several minutes "after which the individual may experience panic symptoms and the realization that the distorted perceptions were false" . When there is an absence of narcolepsy, sleep paralysis is referred to as isolated sleep paralysis (ISP) . "ISP appears to be far more common and recurrent among African Americans than among White Americans or Nigerian Blacks" , and is often referred to within African American communities as "the witch riding your back"
Does anyone here besides me have this condition.
