The connections in my brain that made me me will fail and I will cease to exist, same as before I existed.

The ~40% of me that are Microbes are going to have a field day.

Either of two things:

Nothing. However, I don’t think most people quite grasp the meaning of that. Kind of how they think that before the big bang there was just empty space. No, empty space is not nothing. There’s no empty space, there’s no time, there’s nothing. By definition it cannot be experienced. Experience simply ends. It’s as if nothing ever happened. The universe could just as well have never existed.

The more optimistic theory is that consciousness is in a way immortal. You can only experience being, not not-being. It’s kind of how when you go under general anesthesia and then wake up it’s quite unlike sleeping. When you’ve slept you have the sense of time having passed in between. With general anesthesia this is not the case. One moment you feel sleepy and then you wake up in another room. From your subjective experience you never lost consciousness to begin with. Whose to say that something similar doesn’t happen with death. Instead of experience ending it just moves elsewhere. It’s a pretty difficult concept to explain but it’s somewhat similar to the idea of quantum immortality.

Its a state equivalent to before you were born. Its feels exactly as it felt back then. That is the nothing.

You become what you were before you were conceived.

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.

Sounds like someone elses problem at that point.

When you die you simply wake up in the nearest universe where you didn’t die.

Death is an objective event. It never happens subjectively.

In everyone else’s experience, you die. Your body becomes a corpse and you are no longer there.

In your own experience, you don’t die. The gun doesn’t fire. The car crash never happens. You somehow walk away from the train derailment. Your cancer clears up.

Death exists for other people, never for the self.

Eventually, you become the only living human. You are eternal.

After millions of years, you accumulate enough power to create new people. You do this so you don’t have to be alone. You are now God.

My family will be very sad.

The game will be over, I will remove the VR headset, and continue living my real life. I’m sure in time the memories will fade.

You don’t experience anything, not even a sense of ‘nothing’.

Sweet, silent oblivion.

If I’m wrong I’m gonna go full on Karen on whatever jackass is in charge.

Nothing.

It’s just nothing.

Asking what you experience after death is a nonsensical question, you don’t experience anything at all.

What did you see/hear/feel/experience back in 1066 during the Norman Conquest of England?

You weren’t there, you weren’t alive then, so you didn’t experience anything at all.

That same sort of non-experience is what awaits you after death.

Either nothing or everything.
