My actual point was that symbolic dreams of that sort probably are not "psychic" phenomenon. The cases where people dream about what is coming in vivid and realistic terms are arguably psychic events where somehow someone has literally seen the future before it happened. The symbolic dreams are likely predictions of the sort I described above: The mind crunching data and spitting out graphics that serve as an information dense summary of the mind's conclusions.
They are a form of thinking, not some kind of magic voodoo whatever. And they constitute the vast majority of reported predictive dreams.
As detailed above, it's something I've studied. So I don't think I'm making assumptions. I think I'm making inferences based on the best research and data that I'm personally aware of.
Among other things, I was Director of Community Life for The TAG Project for a time. This is an organization that serves the educational, social and emotional needs of the gifted community. We talked a lot about how brains worked, among other things.
I also founded and ran an email list for a time called Wired For Science. It was designed to serve the needs of my oldest son and members were generally a parent and child or a parent and both of their children or two parents and their child. It was a family discussion group for people living with various neurological issues, such as ASD and OCD.
We posted articles about neurological research and discussed what it means in human terms to actually live with stuff and talked about what the research could tell us about how to more effectively cope with such issues.
You are, of course, entitled to your opinion. So I guess this is where we agree to disagree and I go off and do other things.
That's because symbolic form can be interpeted in many ways, so it's easy post-factum to interpet them in a way that predicts the future :)
