Everyone Experiencing Everyone's Lives

[Envix]

So I've been pondering this question for a while:

as time does not exist beyond the physical plane, couldn't one be reincarnated as someone from the past?

(I personally don't see time as linear, nor cyclical. In fact, I don't even believe time exists, as the past nor future ever exists in the present, which is all that exists.
though in saying that a generation of people that no longer exist have created a generation that currently exists, time would dictate that the past has created the present.
(I'm one to put myself at both sides of a debate))

anyway, this question lead me to a thought.

what if life is an endless process of reincarnation of every sentient being from the beginning of time until the end?
-that we are all one consciousness experiencing itself through the life of everything that has ever existed, and everything that will exist, forever.

This thought came to mind as I crossed paths with a man walking opposite my direction on the sidewalk. As we shared eye contact and nodded our heads at each other, I wondered if I ever had, or if I ever will live their life.

I hope this makes sense. It's very difficult to explain.

On one hand, what you are saying could imply that one has no free will. One experiences a predetermined life. Living somebody else's life makes no sense to me, seems pointless.
Unless you mean you are simply the same entity incarnated in the same time frame.

Or it could be interpreted this way: that you are incarnated into a body with the same starting conditions as say Julius Ceasar, and then you live that life in an alternate universe than the one we know here and now. You have free will and will make choices that will end up with different outcomes. This would be far more interesting and meaningful in my opinion.
