The soul has a former history. It has already experienced a whole series of incarnations, and everything that it experienced in the various lives, the good as well as the bad, is stored in the subconscious. Thus when we see the light of the world as babies, it isn’t for the first time. Even though we have to learn everything all over again, the soul is already many layers deep. 

Let's start with description, What's Past Life Regression?

Past life regression is a technique that uses hypnosis to recover what practitioners believe are memories of past lives or incarnations, though others regard them as fantasies or delusions or a type of confabulation. Past life regression is typically undertaken either in pursuit of a spiritual experience, or in a psychotherapeutic setting. Most advocates loosely adhere to beliefs about reincarnation,though religious traditions that incorporate reincarnation generally do not include the idea of repressed memories of past lives

n ancient Indian literature, the Upanishads mention past-life regression, but the Yoga Sutras of Patañjali discuss the concept in greater detail. Written during the 2nd century BC, the Hindu scholar Patañjali discussed the idea of the soul becoming burdened with an accumulation of impressions as part of the karma from previous lives.Patañjali called the process of past-life regression prati-prasav (literally "reverse birthing"), and saw it as addressing current problems through memories of past lives. Some types of yoga continue to use prati-prasav as a practice.

MY PAST LIFE AS A WWII GERMAN SS OFFICER

WHO AM I?

In this life, I'm a happy, healthy, reasonably normal person. I am educated, manage a business, am happily married, own pets, have many hobbies, and get along with most everyone. I am NOT a Nazi in this life, nor a racist. Although I happen to be Caucasian, (with the exception of having a full-blooded native american grandmother on my mother's side) I am not a white supremacist. I have no German ancestry by blood that I know of. I have a good sense of humor, and do NOT obsess over WWII. (Well, I'm a little interested, naturally, but not as much as the majority of military hobbyists or enthusiasts.) I'm moderate in my politics, and don't happen to own any firearms or a collection of Nazi paraphernalia.
