Regression Therapy - Ever Experience It?

I have been in therapy for quite some time to deal with depression and some other issues. Today for the first time, I had Regression Therapy. I didn't know what to expect. I thought that I would be totally hypnotized and not remember anything after I "woke up". But, it was very different. I felt like I was able to go back in time and relive events of my life that I only partially remembered, but it was as if I had an out of body experience. I found it very beneficial to help me deal with issues from my past. It also had nothing to do with past lives, but the very early stages of my life, including conception. It's tough to describe, but I feel "lighter". Has anybody else had Regression Therapy and how was it for you?
