As I was falling asleep, the strangest concept flitted through my head. That for every tiny, uncountable fraction of time there existed a consciousness that was living my life just a fraction behind me, and a fraction ahead of another. All moving forward to old age, but never quite touching one another.

A chain of these "mes" stretched out behind me to my birth, and ahead of me to my death, and I saw that this chain would always exist, that my lifeline was a stable object in a universe crafted of threads of years.

Somewhen, a me was being born, and a me was dying, and a me was living all the points in between, and it would always be so.
