Yes. You are put in a trance and instructed to recall your past life, with help of some symbolism. First the earlier events of current one, than the previous one, and maybe further. Didn't work for me when I tried a while back, though. Some report that the "past lives" they see make sense and explain some of their quirks. The brain is really good at coming up with explanations, though, so I'd take it with a huge grain of salt.
