Is time in space/time a linear construct?

[Doomchief]

and there are moments where i am already dead.

As we bring into incarnation about 80% of ones total energy, the remaining 20% is always present in the time/space even if the indigo ray during the lifetime is not used.
Sometimes I meditate on the understanding that I am reviewing my experience and this very moment after my incarnation ends. Sort of greeting myself at the other side.
