Hi Joop,
Nice to hear from you. I don't know about the theory, need to think about it more, but your description of early morning experience of PD is so like mine as to be uncanny!! So in fact it is something we have in common, and to guess from many people who have posted over the years a lot have experienced.

Am also interested in your theory about about observing a society from within.

With a disease like PD that manifests differently in so many people, yet has clinically observable similarities, it is time we were 'observed' for more of the similarities - they might start finding answers!

You are always an interesting thinker......
