Sleeping conscious but unable to move is medically known as sleep paralysis, and folklore says it is called ghost pressure on the bed. It is mainly caused by the fact that when a person’s consciousness awakens from sleep, the motor center fails to awaken at the same time. Human sleep is divided into slow-wave sleep and fast-wave sleep, generally the deeper the sleep the lower the muscle tone; but fast-wave sleep is paradoxical, fast-wave sleep EEG performance is actually close to the waking period of the EEG, but in terms of the whole body’s muscle tone, the muscle tone is the lowest throughout the sleep period, so if it is awakened during fast-wave sleep and the muscle tone associated with fast-wave sleep is lowered, and inappropriate sustained If you are awakened during fast-wave sleep and the muscle tone associated with fast-wave sleep is lowered, and if you are not properly and continuously in an awakened state, you will have a state in which your consciousness has been restored but your body is not able to move, that is, your brain is awake but your body is not awake, and in some cases, this is accompanied by hallucinations. This is a normal physiological phenomenon, which may be related to stress and fatigue, so there is no need to be too nervous, and there is no need for any special treatment.
