hypnosis would be the main way to get more info on one's own subject. but not all people are amenable to hypnosis. i went to a hypnotist who specialized in past-life regressions and got nothing out of it because i am not hypnotizeable. for hypnosis to work with me, i was told i needed to see a shrink who could administer sodium thiopental. otherwise, my aching back always keeps me in the here and now. either that, or i just fall asleep if i am a bit fatigued, and get absolutely nothing out of it.
i fail to understand how something on the web could tell anybody about their own past life, with any accuracy.
