Half of the time I look forward to my death, it doesn’t scare me since I don’t see the real point of my life, what scares me is if my agony would be slow and painful.
But then what? I just stop existing and it’s like I fell asleep? Do I see light? Darkness? Nothing? What is nothing?
“What happens when you die” - I assume you mean after you die (not during), and to your consciousness, your awareness rather than your body.
The same as before you came to be. Not like you fell asleep; you’re gone.
