Our brain has four general states of operation: Full Conscious Awareness, the Hypnotic State, the Dream State, and the Sleep State. These states are characterized by different type of electric activity in brain and are defined by frequency range obtained by EEG.
First state - Full Conscious Awareness- our mind is attentive and uses logic to reason, assess, evaluate, and make decisions.
Second - Hypnotic State-, memories become easily accessible and more new information is stored because the door between conscious and subconscious is opened. The person is not really "thinking" in the traditional sense but "experiencing" without critical judgment or analysis or questioning because the conscious mind is not getting in the way. Every time when we getting from first level to Dream State(third state) or Sleep State(fourth state) levels we pass through the Hypnotic state.
We are in this state whenever we are completely absorbed by movie, show or person. Therefore we stop judging and we believe that’s true whatever we see or hear. Our conscious is off every time when we see something extraordinary: very nice car, a beautiful woman, very high, very big, very nice, very ugly,very strong, very bright, very interesting, very famous individual, and anything very - very. Commercials work that way.
