Where were you - your soul, your spirit - before you were born? If the soul is immortal, did it have a "life" before your birth?

Much has been written, and many anecdotes recorded, of the near-death experience (NDE). People who have been declared dead and then revived sometimes report an experience of being on another plane of existence, often meeting deceased relatives and beings of light.

Rarer, but no less intriguing, are stories from people who recall an existence shortly before their births into this world - the pre-birth experience (PBE).
Most memories of a recent pre-birth existence come from children who reveal their recollections spontaneously and without prompting. One such case, from a woman identified only as Lisa P., is told in the book, Coming from the Light by Sarah Hinze:

I was putting three-year-old Johnny to bed when he asked for a bedtime story. For the past few weeks, I had been telling him of the adventures of his great-great-grandfather: a colonizer, a soldier, a community leader. As I started another story, Johnny stopped me and said, "No, tell me of Grandpa Robert." I was surprised. This was my grandpa. I had not told stories of him, and I could not imagine where he had heard his name. He had died before I had even married. "How do you know about Grandpa Robert?" I asked. "Well, Momma," he said with reverence, "he's the one who brought me to earth."
Some experiencers claim to have been given a preview of their coming lives, as in this story at Prebirth.com from Gen:

I remember someone talking to me, not with a voice, but more to my own mind, that it was not good for me to choose who was my parents, that it would not work out. And I was insistent on coming into my family, and it would not work out between my mother and father. I remember being shown various things and places that have happened in my life, even down to the house I live in now
