After much study and research on these subjects, and a few other people's findings, it's my understanding that no one reincarnates. An aspect of you _(we all have many different aspects to our self)_ may choose to incarnate and have its own human experience, but that is not you. All aspects of the self hold the same cellular memory. Thus, they remember your life and your experiences as if it were theirs. Although each aspect, or alternate self, holds its own individuality, each express similar tone and vibration qualities. But there's more to this. Now, we need to understand that linear time is perception that we experience. Thus, we need also understand that all our so-called past lives are actually being experienced simultaneously by different counterparts of our individual essences. Their experiences also become our experiences, just as our experience become also their experiences. Think of your hand as your essence _(wider self for some ppl)_ and your fingers as your essence. You are one of the fingers having this present experience. The other fingers of that same essence are simultaneously having their unique individual experiences within different timeframes which we believe to be following linearly but are not. When you and all your counterparts are done with your individual experiences, you, or your essence _(you are your essence. There is no separation)_ are done here. There is no need to come back and experience something you, or your other yous, have already experienced. There is an infinite number of other realms out there awaiting to be explored. Note, your essence's counterparts are different from your alternate selves.
