Dear Cristi
There are nicely presented problems on the way to physically explain consciousness. It seems that you are not sure, what is the answer. For instance Dawkins is almost sure, what the answers are. :)
As a detail:
You wrote about down-top causation, how details of quantum physics are un-important in classical physics. But if we assume that quantum consciousness exists this is something from quantum level, what remain in classical level. There are still some physical experiments, like interference, which show quantum physics on macro level.
But in my old essay I wrote one sentence and now you and Ellis write a similar sentence:
Kokosar: Let us assume that there is a woman Desiree who is never awake and only dreams. As a consequence, her ego would be weaker. Thus, this is one hint that differentiation and integration are important only because of memorizing of qualia.

Stoica: If one would dream his entire life, and the dream would be consistent, then wouldn't that person experience imaginary as real?
More in my essay and in other my links.
