The Mechanism of Nightmares

During a nightmare, when the body cannot move and the mouth cannot make a sound, it is because the body is being controlled, and the superior mental faculty within the brain is being dominated; in some cases, the mental faculty itself is being controlled by spirits.

When the body is controlled, it becomes unable to move or moves involuntarily, manipulated by the mental faculty of spirits or deities. However, consciousness remains very clear and aware, and the mental faculty is also capable of perceiving this.

When the mental faculty is controlled, not only does the body become unable to move or move involuntarily, but consciousness, speech, and thoughts also become involuntary, manipulated by the mental faculty of spirits or deities. Physical, verbal, and mental actions are all involuntary, and consciousness is often unaware of them. Once awareness arises, if the mental faculty possesses sufficient strength, it can break free from the bonds and regain autonomy.
