Michael Newton, Ph.D. was a psychologist, master hypnotherapist, and teacher for more than forty years. In his book, Journey of Souls, using his groundbreaking hypnosis techniques, his subjects described life after death.
He writes, “In the early days of my studies of souls, I half-expected that those subjects who could recall other worlds would say they had lived in our galaxy within the neighborhood of the sun.
This assumption was naive. Earth is in a sparse section of the
Milky Way with only eight stars that are ten light years from the sun.
We know our own galaxy has more than two-hundred billion stars within a universe currently speculated at one-hundred-billion galaxies.
The worlds around the suns which might support life are staggering to the imagination. Consider, if only a small fraction of one percent of the stars in our galaxy had planets with intelligent life useful to souls, the number would still be in the million
s.
From what I can gather from subjects willing and able to discuss former assignments, souls are sent to any world with suitable intelligent life forms. Out of all the stars which are known to us, only four percent are like our sun. Apparently, this means nothing to souls. Their planetary incarnations are not linked to Earth-type worlds or with intelligent bipeds who walk on land. Souls who have been to other worlds tell me they have a fondness for certain ones and return to them (like Earth) periodically for a succession of lives. I have not had many subjects who are able to recall specific details about living on other worlds. 
However recently, I had two subjects who were best friends and came to me at the same time for regression. Not only had they been soulmates in many former lives on Earth, but were also mated as fish-like intelligent beings in a beautiful water world. Both recalled the enjoyment of playing underwater with their strong appendages and coming up to the surface, ‘to peek.’ I suspect it was not Earth because I have had others who tell of living in an aquatic environment they know was unearthly. From what I can gather, souls are sent to any world with suitable intelligent life forms.”
