> Basically, why is consciousness always attached to the same physical body? Why can't I ever wake up in someone else's consciousness? How does "my" consciousness know to come back into "my" brain whenever I lose it (through sleep or injury, etc).

Maybe it's not attached to the brain, but rather produced/created by your brain?

I agree that there is no self. But that is different from consciousness.
