There is a saying that there is a "soul" after death, also called a "ghost". A "ghost" attached to a normal person is called a "ghost upper body". When "brain waves floating independently in space" forcibly occupy someone's brain, the original brain waves will be temporarily covered, people will temporarily lose their original consciousness, and their behavior will be controlled by the occupied brain waves. That man is possessed by a ghost.
