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…
You might regret that when you wake up on a life raft in the middle of the ocean with a family of just as confused German tourists, as your subconscious has predicted and is trying to prepare you for.
