Sleeping and having nightmares every day, I can't open my eyes, just like a ghost pressing the bed. It's uncomfortable to hear the alarm. What's going on here?

Your nightmare is a ghost bed, also called sleep paralysis. It is a special kind of cerebral ischemic syncope that easily occurs when people sleep, and there is consciousness. Among them, sudden and terrible dizziness will cause a sudden dream of seeing a terrible devil, and terrible palpitations with rapid heartbeat will cause a dream of being chased by a terrible devil. After waking up, temporary blindness will cause the illusion that you can't wake up. Usually, people will lose consciousness completely when they syncope, that is, patients will feel fine when they syncope, and after returning to normal, they will curiously ask the people next to them: Why am I lying here? I didn't know that I had just fainted until someone next to me reminded me. Often the biggest possibility of a ghost bed is that the pillow on the bed is too high, which leads to neck flexion and compression and poor carotid blood flow. Whoever sleeps with a pillow too high will often have a ghost bed. When I was a child, I changed a particularly high pillow in summer. Therefore, ghost beds appear frequently day and night. Another reason is low blood pressure. For example, when the weather is hot, everyone's blood pressure will be lower, and it is more prone to ghost bed pressure than when the weather is cold. In short, the ghost press, like all psychological activities, is an illusion caused by the stimulation of objective things, such as the dream of finding a toilet is caused by the stimulation of objective things such as urgency of urination, and the dream of feeling cold is caused by the stimulation of objective things such as cold night and thin quilt. You can't keep your eyes open because your vision is impaired during cerebral ischemia, and you hear the alarm because of tinnitus. In short, all dreams are hallucinations caused by the stimulation of objective things, such as the dream of finding a toilet is hallucinations caused by the stimulation of objective things such as urgency, and so on. If you don't feel dizzy during the day, your ghost bed can only be caused by sleeping in the wrong position or the pillow is too high, just like the reason why I have a ghost bed every night.
