I gave you an example, qualia. I gave you another example, the philosophical zombie problem. The latter has real implications, how can we know whether or not a coma patient is conscious?
There's new evidence to support the idea of quantum effects in the brain. Far from conclusive, but it does give a little credibility to the idea.
There's also a hypothesis that the electromagnetic field produced by the brain could be the "carrier of conscious experience", which would at least solve the binding problem.
But you're very hand wavy and simply disregard my examples. Instead, you throw around the word "mystical" without giving a clear definition, which makes it too easy for you to move the goal post. And then you simply refer to the brain as a "bag of stuff", which is a gross oversimplification.
