What Is Sleep Paralysis?

Isolated Sleep Paralysis

Sleep paralysis

This is medically called "the nightmare (tone eye)", also known as the "ghost press". Like dreaming, nightmares are a physiological phenomenon. When a person suddenly wakes up from dreaming, part of the nerve center of the brain is already awake, but the nerve center that governs the muscles has not yet fully awoken, so although he feels uncomfortable, he cannot move. One nightmare will disappear immediately.

Basic overview of sleep paralysis

Isolated Sleep Paralysis

When you fall asleep, you may unintentionally put your hands on your chest, so that you increase the burden of breathing, and the heart is stressed. Therefore, the blood flow will be slower and the brain will be hypoxic. In this case, the body will be very unconscious Yes, so it felt like a so-called ghost press. Some people are also accompanied by cold sweat, hypoxia, and even hallucinations caused by rapid heartbeat. These are all caused by poor sleep habits, so it is important to adjust your sleeping position. Of course, it is not excluded that some people have sleep problems caused by organic lesions, and sudden death can occur severely. . . .

Sleep paralysis pathology

When sleeping, the human motor center will be closed to prevent the dream movements from being reflected in reality and causing harm. Sleep paralysis syndrome occurs roughly during REM sleep. People will dream during this sleep stage, so the brain temporarily suspends our ability to move, so as to prevent us from making limb movements that may hurt ourselves in the dream. It's a clever little mechanism, but if it doesn't work, you'll do something in sleep, and when you wake up, you'll feel paralyzed. When this happens, the state of sleep will extend into the awake state, resulting in an abnormally realistic illusion, the degree of clarity is much higher than our memory of dreams.

Sleep paralysis syndrome means that you are awake, but the center of movement is still closed, so although you wake up, you ca nt move your whole body, only the eyes and eyelids can move. The most terrible thing is that while sleep paralysis is often accompanied by auditory and visual hallucinations, you will hear fine human voices and ghost images.

Sleep paralysis syndrome usually occurs during sleep. It can block our ability to behave, so that we don't really act in our dreams to avoid harming ourselves. Normally, sleep paralysis subsides after we wake up. But it is not always the case, and one in three people will occasionally wake up before the sleep paralysis has completely disappeared.

This supernatural concept is not unique to Western culture. In China, the pre-awakening hallucination is called "ghost pressure", while in Japan it is called " ( )", also known as "metal bondage". The eighteenth-century English phobia was a demon who attacked women when they fell asleep and made them unable to move. In Newfoundland, a similar demon known as the "Old Witch" appears as a scary witch, sitting on the chest of a sleeping person. In China, it has been said for centuries as a "ghost press". Zanzibar has "Bobova"-a flying little dwarf.
