It depends on what it really is, is brain a movie projector that projects as "external reality" any possibility all of them real out of a myraid of possibilities, that we see through our senses as external reality? If so, if you could see reality as it really is, the only thing you would see, would be random waves interacting upon each other and collapsing, a sea of vibration without any definite state.

Or is our brain a movie projector that is reading already definite bits of information and effectively giving us an accuarate image of reality?. In this case though still reality would really look like no more than waves collpsing said waves had an already set pattern and information.

So are we making up our own movies? Or are we actually projecting an already inserted movie tape?

EDIT:

About "other people"? I dont know, guess each would have their own movie projector, it would be irrelevant if we are already "playing" the same movie that was pre-set. But if we make up our own movies and project them outwardly, how would that explain other people and the consensus reality?

Or is it, that really when we interact with other people we are just exchanging common perceptions? Questions, questions, questions.
