No such thing
Once you die, you'll be gone; decomposed and maybe remembered.
Maybe in your death bed you'll come to this. Maybe you'll still be delusional, and before you know it, you'll die and you'll die delusional.
We can not know if we have some kind of "life" or existence after death, so claiming that we just sieze to exist completely is irrational because it implies that we know every part of the human existence (and.. we don't!) and it implies that we have references that proves the termination of all of those parts after death.. Which we don't have.
Claiming with certainty that nothing happens after the body stops to support earthly life = just as stupid as believing in an "afterlife" with certainty.
On another note, claiming to know not only know with certainty that something does happen, but EXACTLY what happens = madness, which religion is.
