Age regression in hypnotherapy supports the client to experience an event in an earlier time as if it is occurring now.
A hypnotized person is given suggestions of a younger age so that the client can relive certain experiences events from a more resourceful state.
In case the client reacts as he did when he was at that younger age, but views the subject matter with his present maturity, it is called behavioral regression.
If the client feels that he is actually at the younger age, it is called revivification regression.
