something something. dont they have those quantum theories?
In the quantum theory called the Many-Worlds Interpretation, every possible outcome exists in different branches of reality.
So when you dream something horrible and wake up relieved, it almost feels like your brain briefly experienced a different possible branch - then snapped back to the one where everything was okay.
Not actual proven physics of course… yet…
Haven’t seen that movie. Is the premise that reality only exists as subjective experience, and a real, physical word outside of our minds is an illusion?
Sorry to give you a cliché/unhelpful answer but; the movie plot is sort of a character dreaming, or rather, being stuck in a dream unable to wake up. He floats through the city meeting people he both does and doesn’t know and listens to their “bit”.
Some of it is absurdists while other parts are really insightful. I’m unsure if you watched the video I linked but it starts with one of my favourite quotes from the film;
‘They say that dreams are only real as long as they last. Couldn’t you say the same thing about life?’
If you get the chance and haven’t seen it I’d really recommend it. If you enjoy the rotoscoped animation but want a more “grounded” story A Scanner Darkly is also worth checking out.
