I don't have anything that painful to relive... Then again, if you believe in past lives...
But to answer your question, I do relive some parts of my life, usually the bad ones. Sometimes I can figure things out by replaying them in my mind, and just as often it's just futility.
I'm not a therapist, but I'm a sucker for helping people. Chat with me if you want.

If you haven't checked out Lucid Dreaming, you will love it. Lucid dreaming is controlling your dreams :)
Research it a bit :p
