Hypnosis is a relaxed state where someone is more open to suggestions. It feels familiar because we actually do it so often. We enter and leave hypnotic states constantly throughout the day. The act of reading, day dreaming, or watching TV with focused attention are all light trance states. Walking down the sidewalk or waiting for the subway, many people are in a trance state. Just look at them. Driving on a highway may make the trance state more easily noticed.
