We probably know what you mean (and agree), but the Empress Theodora

and I agree with her majesty. Your use of "universe" seems strange,
but I've also heard people use "world" in the same way, e.g., "I was
immersed in the world of dungeons and dragons", or "we're each in
our own world".

I will adopt your usage. It was said that painters portrayed a scene,
or a face, but I'll drop the confusing usage.

Can you give some examples of things in your mind that are
sentient beings but who are not you? I thought that only
some MPS patients had that kind of thing going, and even
they are under suspicion for having made it all up.

I don't think that you have any evidence that any human
being has ever hosted a separate sentient being or personality
after having watched a performance.

That's the point: puppets on their own are empty. I needed
a word that distinguished someone you might know in a simulated
Earth that you were living in, but who wasn't really a separate
person (i.e. he was not being emulated). This person has only
the appearance of being a real person. In reality, he's a puppet
being controlled by the operating system.

Thus if you have two brothers that you've grown up with, and
then you find out you're living in a simulated Earth, it might
further turn out that brother A is real, has actual experiences,
can suffer pain, and so on, but that brother B is a complete
fiction.

Yes, but you can see that one *might* speak of the entire
Earth or city or whatever as being an emulation, if it
emulates everything within it. Of course, why emulate
a street-car within a simulation, when it need only be
portrayed? All that is important to the real emulations
(i.e. the people and animals) are the gross characteristics
of the street car.
