You may not understand why I ask the question if anyone can remember being dead.
I don't think it's a question of understanding, it seems to be an entirely different set of perspectives.
For me? The most important thing is that the universe is an unimaginably large place full of wondrous things that I will not live long enough to discover - no human ever can. My place in that universe is infinitesimally small. Some people might say that makes me insignificant and of no consequence but that's not true - it's simply a question of scale. I am significant in my own and many other people's lives.
But our lives, all of them, are tiny whether you look at them from the aspect of age of the universe, size of the planet/solar system/galaxy, scope of human history.
When it comes to perspective, keeping an eye on both the personal, particular, local and family and simultaneously accepting the gigantic, magnificent, universal, unknown and incomprehensible ...... and still feeling that what you do and think and feel is important ...... is the trick.
I suspect that some people I've met (and many I've read) never feel this way. For them, the focus is first and always human consciousness, and especially their own perceptions and consciousness.
