Yes, in addition to the symptoms of fast heartbeat when the ghost presses on the bed, there are also symptoms of terrible dizziness, neurological dysfunction such as being unable to shout or move, and visual impairment such as being unable to see anything after opening the eyes. These symptoms are caused by cerebral ischemia. The main causes of cerebral ischemia during sleep are low blood pressure and improper sleeping posture or too high pillow, which causes neck flexion and poor blood flow.
Ghost pressing on the bed means that you suddenly become conscious but unable to move your body while sleeping. In fact, you are suffering from a sleep disorder. The phenomenon of "ghost pressing on the body" is a symptom of sleep paralysis in sleep neurology. When the patient is sleeping, he is half awake and half asleep. The brain waves are the amplitude of wakefulness. Some people also have images. Hallucinations, but with minimal muscle tone throughout the body.
Medical explanation
Ghost pressing on the bed means that you suddenly feel conscious but cannot move your body while sleeping. In sleep neurology, this is a symptom of sleep paralysis. The sleep cycle consists of falling asleep, light sleep, deep sleep, deep sleep, and finally the rapid eye movement (dreaming) period. Sleep paralysis occurs during the rapid eye movement phase of the sleep cycle, which is when we fall into deep sleep and begin to dream. During rapid eye movement sleep, people's dreaming activity accelerates and the body's voluntary muscles begin to freeze. This temporary paralysis sometimes causes the patient to remain unable to move after waking up from the dream. During the rapid eye movement period, our skeletal muscles, except for respiratory muscles and eye muscles, are in a state of extremely low tension. This is a protective effect that prevents us from harming ourselves or the person next to us by acting in response to our dreams. Sleep paralysis is caused by unknown reasons during the rapid eye movement period. The consciousness has awakened, but the muscles of the limbs are still in a state of low tension, resulting in a situation where the person does not listen to the commands of the consciousness. Hallucinations often occur due to abnormal conditions in the body that the brain cannot explain, coupled with fearful fantasies.
Ghost press may occur during lunch break and night sleep. In fact, this situation has nothing to do with ghosts at all. It has a formal scientific name in medicine: sleep paralysis.
Sleep paralysis usually occurs when just falling asleep or about to wake up. The patient feels that he has woken up. He can hear the sounds and see the images around him, but he cannot move or make any sound. Sounds are sometimes combined with hallucinations. Most people will feel panicked at this time. Fortunately, most people will slowly or suddenly resume body movements within a period of time. Because of the panic at the time of the attack, many people will feel scared after waking up, and intuitively think that it is caused by being suppressed by some unknown object, so there is a saying of "ghost pressing on the bed".
Countermeasures
If symptoms of sleep paralysis occur, you can quickly restore your muscle tone in the following ways: First, quickly turn your eyeballs and make them move in a circular motion, making them go up and down. Move left and right. Then, blink, contract the muscles around your mouth, move your jaw and tongue. When muscle tension begins to appear, move your neck, shoulders, hands, fingers, legs; ankles and toes. Finally, sit up and move everything. Muscle
