This is a question that has been plague-ing my mind for days. But first, let's imagine a scenario:

* You were alive
* You died
* But… when you died… you (have / had) no clue you died… because, the simulation just continued on… i.e., you don't remember transitioning from *the world of the living*… to… *the world of the dead* (A-K-A the afterlife)
* So, you are currently in *the world of the dead* and everything looks and feels the same, as it was, in *the world of the living*.
* What are some key details or differences, you would look for, to determine which "reality / world" you're in?
* I am also going to remind you of 3 movies which coincide with the idea I'm presenting here: The Sixth Sense, Beetlejuice, and the TV show "Lost"…
* In these 2 movies, and that 1 TV show, the people didn't know they were dead. It took them some time to figure it out… and that's EXACTLY why I'm asking you this… 
* Let's also consider this: When you were born, it was a traumatic event. An event so traumatic, that your brain *chooses* to not remember it.
* I can only imagine that… if you were to die, your brain (conscience) would do the same thing again… i.e., dying was such a traumatic event, that your brain (conscience) chooses to not remember that event either.
* How would you know the difference, if both "worlds / realities" are identical, and you don't remember dying… i.e., that transistion?

If you think everything is a simulation… how would you determine if you're alive or dead? What details would you look for?
