Of course this assumes such a thing as reality. Philosophizing is a real pain when one agrees that nothing exists. However, we all can assume certain givens, and then proceed happily.
So there is reality. I certainly don’t agree with that scenario but how am I going to do a piece on mirrors of something that doesn’t exist? Hold on, I’m having a thought. (Yahoo Serious, Young Einstein).
So the mirrors would have to fit nicely in the category of things that aren’t real but reflect real things.
Dream are a shadow, of something real. (Gulpilil’s character in The Last Wave.)
So how did I wind up on dreams?
Free association. Dreams are made up of the brain’s interpretation of reality in a reflective way despite being largely construed as meaningful information being perceived by the sensitive types.
Dream time is real, a real reflection.
