Hypno Drama requires a skillful hypnotherapist to conduct. It is a process where the hypnotized person is brought back in timeline to a time where an incident occurred (usually a traumatic experience). The person is then told to re-live the experience. The hypnotherapist will give close guidance in an attempt to change how the person perceived the incident so that she can then handle it differently.
Since recalling or reliving the sad experience can cause emotional outburst, this process is best be conducted by an expert with many years of age regression experience.
