This is interesting. It reminds me of dreams - I wish I could lucid dream!
If our brain is a quantum computer maybe dreams are possibilities we "see" as glimpses in parallel universes?
Dreams have always puzzled me.
They happen completely outside of the memory of our everyday life.
You are just there faced with some situation that is unfolding, having no idea how you got there, but rarely question anything. It just flows and then you wake up.
Doesn't seem like brain has anything to do with it. More like an out-of-body experience somewhere else, while body is asleep repairing itself after a long fruitful day, though we might still be tethered to it on some level.
