This is an excellent post! I'm upvoting and I promoted it for you.
The post reminds me of a quote...

All that is ever seen or seam is but a dream within a dream.

There are cultures in this world that believe that the waking state is what is unreal and that the only reality is the dreaming.
Neil Gaimans Sandman series was very influential in my life in the way that I think about dreams and the dreaming.
