How to see past lives?

What are the best methods of vividly exploring your past lives?

Meditate and focus on remembering the life before the one you have now, then the life before that and the life before that....etc. It would be just like your normal memory recall, but uncontrolled.

Thats how past life regression usually works, unless you want to pay someone to hypnotise you into an altered state of consciousness...though aided regression can sometimes allow a persons mind to play tricks, so I'd suggest the first option.

I've also heard of searching through dreams as well and re-creating the scene from subconscious memory, but I am pretty sure that that technique could be a bit unreliable since it is often hard to tell whether a person is dreaming of a memory, or just dreaming.
