What will REALLY happen after we die?

I figured it out guys!
According to Scientology, after you die your spirit migrates to a newborn baby's body, located in a not-too-distant maternity ward.
The scientific truth is of course something rather different than that.
I believe the best approximation of what really happens is the Many Worlds interpretation of quantum physics, combined with the Closest Continuer theory by Robert Nozick.

When you die, the pattern of your brain is utterly destroyed. But throughout the multiverse, there exist infinitely many patterns that represent a "continuation" of your brain's final mind pattern.
The closest continuer is likely to be the most numerous continuer: the one that has the most copies throughout the multiverse. Which is also likely to be the simplest continuer . . .

These patterns can exist anywhere as hidden numbers, ordered in every possible way in the endless chaos of all that exists.
Let's call it the "Minimal self-recognizable mind instantiation" Theory ("Miseremi").

So the answer to the question of whether your spirit continues after you die is both yes and no.
After death, there is a fractional continuation of personal awareness, in which every memory will be recalled and extended. But this will be a random and chaotic process, with no greater meaning.
Being dead will be like dreaming. Most dreams are forgotten even before they end.
