I believe there is a marriage of time and reincarnation and it is like a river. Flowing with much force through rapids with a smooth pools just beyond. As the river floods in spring, it spills over the banks engulfing everything in its path. All rivers on Earth eventually reach vast oceans and seas. If this water cycle following what we see on this planet as the water cycle, then some of that time will "evaporate" until it forms "clouds of time/memories". As these clouds move over land toward the mountain ranges to dump stored time/memories...snow. Along its journey to the mountains there are releases of "time rain" that falls all around us. I think this could be part of the equation of deja vu. Because time as we know it is a dynamic system.
