They say you die twice. One time when you stop breathing and a second time, a bit later on, when somebody says your name for the last time. - Banksy
Also touched upon in David Eagleman’s book, Sum. Except there were three deaths, the first is when your heart, lungs and brain stop; your physical death, the second is when your body decomposes into something that isn’t “you” anymore, and the third is when you are remembered in the living plane for the last time.
It was pretty interesting; after your first death, you stay in a room with many others, waiting for your third and final death. Naturally, you stay with a lot of historical figures and people that have memorials or other structures built in their memory. They’re usually quite miserable, since more often than not, they’re misremembered or remembered for things they’d rather not be remembered for (infamy, or the way they died).
But once you’ve had your third death, you move into a different room. No one knows what lies beyond because no one has ever come back from it. People usually feel a bit of relief and disappointment once their third death happens, but it’s especially regrettable when you see two well-acquainted people completely miss each other, because it’s usually the last loved one left who holds on to the other’s memory.
