Based off the many worlds hypothesis: Imagine every second is the end moment of time.
So reality is playing out on that time, the present being the end, creating infinity as we move along. So we find ourselves in this world line, our entire life is reduced to 2 Dimensional crease in a block of infinities. Consciousness collects in these creases of compatible world lines. The realities which support conscious eventually grow together (merge with one another) and manipulate their block of reality infinities. The cell is formed once again. and the mission to expand continues.
I guess a constant in alien (as in non-local realities, or extra dimensional) maths, is that it goes from small to larger. We need a concept of small to large, some kind of medium ground to start building a communication, because with different mathematical rules, really ridiculous things can exist.
Imagine 1+1=3. That math would be insane, the classical world it would produce, if any. However, as strange as it may seem, there is evidence that is the math of our non-local reality. It probably wouldn't support consciousness, but perhaps an advanced intelligence with knowledge of manipulating realities, could enter such a reality.
