Regression Therapy
Regression Therapy is a therapeutic tool that uses hypnosis to allow a patient to mentally return to a younger age to recall and examine traumatic events. This allows the patient to gain an understanding of those events (and their current issues) and cope with current problems.
Ultimately, the goal is to recover repressed memories of events from childhood that are having effects on current life functioning. Another controversial use of regression therapy, usually by "new age" style therapists is the attempt to recover memories from past lives as a means of explaining phobias or recurring dreams.
