A more detailed explanation of nightmare symptoms
Nightmare, commonly known as ghost bed, refers to shouting when you are scared in your dream; Or feel something pressing on your body and you can't move. It is often used to describe terrible things that have been experienced. When you suddenly wake up, when your muscles and nerves are not awake, you will be conscious and unable to move.

The cause of nightmares
Nightmares can be said to be a normal psychological phenomenon, which has nothing to do with ghosts. Usually, it is more likely to happen under the conditions of great pressure, excessive fatigue, abnormal work and rest, insomnia and anxiety. Science shows that nightmares are caused by transient cerebral ischemia during sleep. When transient cerebral ischemia occurs during the day, people will have terrible symptoms such as dizziness, palpitation, chest tightness, black eyes, tinnitus and various neurological disorders.
Nightmares are partly caused by incorrect sleeping posture. For example, when sleeping, putting your hand on your chest and pressing your heart will make you feel breathless unconsciously, resulting in nightmares. Sleeping on your back and lying flat at the same time can also easily cause nightmares. Therefore, the sleeping position when sleeping is very important.
