The body cannot move, but the consciousness is awake, which often happens when you just wake up, especially when you wake up from the dreaming period. Because during the dreaming period, that is, the rapid eye movement period of sleep, the person’s brain waves are close to wakefulness, but the whole body muscle tone is the lowest during the whole sleep period, and the myoelectric activity is reduced or even disappeared, so if the person wakes up from this period, the whole body hypotonia is likely to be brought to the awakening period inappropriately, and it will happen that the brain is awake but the body can’t move. When a person has such an attack, it is called sleeping paralysis. During the attack, the person often feels very anxious, very frightened or even near death, and at this time, if someone next to him calls out or touches him, it is possible to interrupt the sleeping paralysis process. Most of the reasons are related to sleep irregularities and sleep deprivation, because the frequency of sleeping sickness is very low and it does not have a serious impact on the body. However, if the episodes are frequent and the patient feels very uncomfortable, medication to shorten the dreaming period can be used to improve the symptoms.
