There's precisely nothing about the conscious mind that would inform the physics of the universe/multiverse to do something different from the unconscious.

No, my mind generates my subjective reality. Or 'directs' me to it.

Too many people have not read Permutation City.

Nobody gets upset because it's possible to count natural numbers out of order; being upset because "oh noes the states of the universe might be out of order" is equally pointless.

I find the universe-jumping upsetting because I don't want to leave my current universe. I'm aware that I 'really have lived' in this universe for my entire life, in the vast majority of my measure, but I don't want to live in another one tomorrow, even if I felt the same way then.

By "universe" I just mean a different measure of universes from my current measure. When I say I will live in another one tomorrow I mean that my measure will shrink during my sleep and join a larger one upon waking; that becomes my universe which I have always lived in for the vast majority of my measure.

I know this always happens on some level but I would prefer a decent amount of consistency, enough that if I could perceive the two branches I wouldn't be able to tell the difference for some time.

(Human language really isn't designed for these concepts.)
