I rather think that there is a common consciousness which our brains focus into individual local manifestations of consciousness in a way similar to how a lens focuses light.
It’s just a feeling that consciousness has to derive from something, and there may be a conservation of consciousness similar to the conservation of energy.
It also might explain how there seem to be different levels of consciousness. In a lower level of consciousness, the brain is acting like a poor lens.
I think we don’t know what consciousness is, but I posit that it is something more substantial than a bunch of electrochemical reactions, although it seems like electrochemical reactions are necessary for its existence as far as we can tell.
