Just shy of two weeks ago, I caught an episode of the YouTube Channel/Podcast "The Rest is Science: Cognitive Ghosts," about weird perceptional things like de ja vous, and the uncanny sensation that there's someone in the room with you. In the very last chapter of the video, They talk about the almost universal experience of people in the process of dying having dreams of loved ones who've died before them.
And they mentioned the hypothesis that it could be the brain's way of distracting the dying person from the physical pain of their body shutting down. Which is lovely to think that your last thoughts in life will be of love. But I also think, that as a uniquely, intensely cultural species, passing on our values and knowledge and life lessons is just as, if not more, important than passing on our genetic material. So our brains go into overdrive, with all the fervor of a salmon swimming upstream -- reminding us of all the most important knowledge we've learned (love each other, forgive each other), so we can pass pass that knowledge on to those who will live after us.
