Sleep paralysis is a common phenomenon that occurs when a person wakes up from sleep but is unable to move their body. Although the brain is conscious, the muscles remain asleep, causing a temporary paralysis that can last from a few seconds to several minutes. The experience can be terrifying, with many sufferers reporting vivid hallucinations that range from demons and ghosts to aliens and religious experiences.
Despite being a common occurrence, sleep paralysis has only recently become the subject of scientific research. For many years, it was an ignored phenomenon, but over the past decade, interest in the condition has grown. In 2020, Harvard sleep researcher Baland Jalal completed what is thought to be the first clinical trial into different ways of treating sleep paralysis.
Scientists believe that sleep paralysis has probably existed for as long as humans have been sleeping, with references to the condition found throughout literary history. Mary Shelley, for example, was reportedly inspired to write a scene in Frankenstein by a painting depicting an episode of sleep paralysis.
For some people, sleep paralysis can be a life-affecting condition, causing fear and anxiety that can impact their ability to sleep. Others, however, become accustomed to the experience, with episodes occurring every two or three nights. While the condition may be unsettling, it is generally not dangerous and can be managed through simple lifestyle changes, such as avoiding caffeine before bed or establishing a regular sleep schedule.
