You got it right; losing your memories is essentially death. However, all humans die, so it’s an all roads lead to Rome kind of thing. You could get a concussion and forget everything, or you could get run over by a car and die. There’s no reason to give memory loss special treatment over other terrible things that could also happen to you.


Uh… that’s literally what a simulation is.
But dreams aren’t simulating reality as we observe it; they just kinda do their own thing. Your brain isn’t consistently simulating quantum mechanics (or, hell, even simple things like clocks) while you’re dreaming so this is a moot point.
