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?
When you die, your brain dumps dopamine and you enter a euphoric state in the brief moments before you’re technically dead.
Time is relative for every entity, according to the theory of general relativity. I posit that as you die, your personal timeline extends to infinity. The state of euphoria is therefore permanent to you, the experiencer. It’s not heaven, but for you it might feel like it.
Additionally, every neuron fires as your brain gives out, so during that personal eternity your life is “flashing before your eyes”. If this reflection on your life fills you with contentment, that is heaven. If it fills you with shame and regret, that is hell.
