How does the brain create abstractions?

1) I believe the brain to be an imperfect inversion of the Universe itself, something like a 3D holographic mirror – as above, so below….

2) I believe dreams and metaphor will eventually be proven central to the abstraction process.

3) I believe this imagaic abstraction process operates like a “clutch” mechanism, in a car for instance.

4) I believe the key to the abstraction process lies in the mechanism which the brain uses to convert words into images, and images into words.
