Yeah, I know this is a bit late, but with this topic, I just have to jump in on it. I have worked with many people on past life regression, and have found that like Jax said, it doesn’t matter if it is your past life or not. You are shown something and can learn from it, regardless.
I would like to say that I have found that the reason that things bleed over from past lives is because we are experiencing the same types of energies that connect with those from the past life. It is the same as when a person is walking through a circus grounds, and smells a certain food cooking, but instead of thinking how good the food smells, they remember eating that food with a long-dead grandfather, or something like that.
Also, it has to do with lessons that were left unlearned in the past. If you refused, or were unable to, learn a lesson in the past, then you will repeat it again in this life. It also has to do with the lessons that we DID learn. We are reminded of the accomplishments that we made in the past and can draw on those strengths in our current life.
Sometimes, it is only the remembrance of the way that a person died, or was “punished” in a past life that keeps us from repeating the same mistake this time around.
Anyways, this is sort of a “thing” that I have, so I had to jump in. Sorry for the interruption.
