Henry Fuseli – The Nightmare (1781)<\/figcaption><\/figure>\nA number of physiological changes occur in the brain during the falling asleep phase and during sleep. When tested physiologically, sleep is irregular during the Rapid Eye Movements (REM – Rapid Eye Movements) period, and if awakened in this stage, “sleep paralysis” is experienced.<\/p>\n
If sleep paralysis occurs during the falling asleep phase, the body is physiologically ready for REM sleep, but the brain is still not shut down. In medicine, this is called \u201chypnagogic (predormital) sleep paralysis. In this case, the brain wakes up, but the unconsciousness brought by sleep comes into play and the muscles cannot wake up.<\/p>\n
The body, called “sleep atony,” causes the body to be paralyzed and even to feel as if someone is sitting on it or a weight has collapsed. This is just like a real paralysis; because the person is conscious that he is awake, but cannot move. If sleep paralysis \u2013 often seen in this way \u2013 occurs before waking, the REM cycle is incomplete; but the brain will wake up from sleep and consciousness will return.<\/p>\n
This is called “hypnopompic (postdormital) sleep paralysis” in medicine. Again, in this case, the person is aware that he has awakened, but the sleep atony is not turned off and he experiences a temporary paralysis. In short, sleep paralysis is a condition that occurs due to the physiological incompatibility of the perceptual part of the brain and the part that keeps the body under control.<\/p>\n

How Long Does Sleep Paralysis Last?<\/h3>\n
Sleep paralysis can last from a few seconds to a few minutes. In very extreme cases, it is also known to last for 4-5 hours. Most people do not experience sleep paralysis more than once in their lifetime. Such single cases are called Isolated Sleep Paralysis. Although not very common, sometimes people with sleep paralysis recur for a lifetime. This is called Recurrent Sleep Paralysis in medicine.<\/p>\n
Isolated Sleep Paralysis is not usually a cause of illness, but rather a natural consequence of our bodies not working perfectly. But Recurrent Sleep Paralysis can be a symptom of a number of diseases. Sometimes hallucinations can occur during sleep paralysis. These can be felt both auditory, visual and tactile.<\/p>\n
Since this situation, in which the consciousness is completely open and the body is locked, is extremely frightening, the brain works fast to protect itself, and some non-existent images appear at the same time. These unreal and frightening images are in one’s own subconscious. These delusions, which even led to the emergence of some myths about the subject, consist of some hallucinations of purely physiological origin.<\/p>\n
\nWhy Are Extraordinary and Frightening Beings Seen in Sleep Paralysis?<\/h3>\n
<\/p>\n
No matter how scientifically explained sleep paralysis, it is a frightening experience due to unrealistic images. Because the individual is aware that he is awake with his sense organs, but he cannot move his body. The individual continues to dream, especially because the REM cycle in which we dream is not completed. At this very moment, some imaginary products such as monsters, creatures, demons and jinn are seen in our subconscious. The reason why sleep paralysis has become a social myth and is called “nightmare” is the unrealistic meaning attributed to sleep paralysis.<\/p>\n
