You know when you're in a high adrenaline situation and time slows down? I imagine it's like that on steroids.

In the real world, one moment we're here, and the next, we're gone. But for the dying, one imagined moment sprawls out to infinity like a single photon stretched out over the endless chasm of space making its impossible journey towards black hole. Death comes slow, and then all at once, we are swallowed by the void. And we become darkness.

As creatures attuned to the light, we find it scary and terrifying, but not being is just another designation of being.

Or put more simply, what were you experiencing the moment you were conceived? It's that.
