This cruel universe I love so dearly

[Purple Rabbit]

As you Kyu said, Pippy, it's not a theory it's just wishful thinking. The most logical is that nothing happens. It's as when you get unconsious. You don't dream or anything.

Since your brain isn't working when you'r dead are you not gonna experience anything when you are dead.

Of course we could all be living in a computer simulation and wake up at death. This certainly is the scenario a god with some awareness on sustainability would prefer, the cosmos seems a rather perverted waste of resources for divine experiments on humans in this deserted corner of the visible universe (some 94 billons lightyears across). But in the end the simulation argument is like the dream argument: possible (in a way yet to be found) but not probable, and certainly nothing beyond speculation.
