David, excellent text. Taking the cue of your slogan (which I love), see if you agree: A possible model of what is happening is that there is an objective reality that is independent from any of us, and that is made of matter. We inhabit this reality, and the matter somehow generates the minds that dream the dream. The hard problem becomes hard because the dream takes a secondary role, and the hypothesized model is taken as the "hard truth". This model is very useful: it is a good way of thinking when one is trying to build rockets or computers. However, it should be treated as a tool and not more than that, until further notice. To tackle the "hard problem", a different tool is more appropriate. This different tool puts the dream at the center of the stage. This should not sound crazy, because the dream is more real, in a sense. We experience the dream directly, while we only hypothesize the objective external world. Different questions can be asked of this model, for example: how does the presentation of an objective external world made of matter arise at the intersection of our dreams? Does this go in the direction of what you are saying?
