Cerebral infarction: it is mainly caused by blood circulation obstacle in the brain or ischemia, hypoxia and other factors, and after the onset of the disease, numbness or paralysis in different parts of the body will mainly occur, and aphasia, blurred vision and so on can also occur. The disease has a high incidence in elderly patients and can develop during sleep. Therefore, it is possible to wake up after a sleep and be unable to move. 2. Cerebral hemorrhage: Cerebral hemorrhage is the rupture of blood vessels and blood flow out, which affects the function of the corresponding brain area, thus hemiplegia, aphasia, headache and other symptoms appear. 3. Sleep paralysis: Sleep paralysis usually shows that the patient is conscious when he/she goes to sleep or wakes up, but the muscles of the body are in a state of paralysis, which makes it impossible for the patient to make normal noises and move his/her body. Patients should consult a doctor when they have the symptom of not being able to move their body after a sleep, so as to avoid delaying the treatment.
