Milton Erickson defines trance state as Active unconscious learning.
First, he believes that hypnosis is of the unconscious or subconscious mind. And everyone has a subconscious mind that is filled with resources. What he needs to do is to learn to communicate with the patient’s subconscious mind, speaks its language and build a rapport. The patient will then draw out from his own experience the resources that provide a solution to his problems.
