Deja Vu, Philosophy of Mind, Metaphysics.

So imagine that the universe IS a simulation, and that that simulation isn't just a view-and-record but is more like god playing a really complex version of The SIMS. So complex, in fact, that it begins to exhibit reflectively epiphenomenal behaviours--that is, something like minds arise out of the the interactions of the system, but they are aware of themselves and can know their own experience and affect the system which gives rise to them.

Now imagine that the game learns, even when new people start new games. That it remembers what the previous playthrough was like, and adjusts difficulty and coincidence, accordingly.

Now think about the last time you had such a clear moment of deja vu that each moment you knew-- you knew--what was going to come next, and you had this sense--this feeling--like someone else was watching from behind your eyes…

Just some thoughts.
