An interesting discussion with a friend stirred more speculation on the nature of dreams. What are they, what causes them, are they one thing, or many?

In 1986, I woke from a dream that made a profound impression on me. Upon waking I had the feeling that I was a witness to a page in my own book, like a time traveler watching a moment from their own life. The dream had nothing familiar in it except for myself, it was not related to a previous experience. So I carried the mystery around for a little while, wondering if I would ever find out what it was about; I didn't assume anything. Only later did I come to an idea of what it might have represented, but I don't know for sure.

At the time of the dream, April 1986, I did not have a driver's license. So a driving dream was not a regular occurrence, in fact I don't recall ever having a driving dream before this one.
It was a magnificent day, the sun was golden, the trees were gorgeous, tall and green, and the air was infused with the fragrance of summer. I was in the drivers seat of a red Volkswagen Beetle, I am not sure of the year, but it was an older one. I was driving for a while, down a country road, enraptured in the beauty of the day. One thing was strange, however; I was not in New England. I was somewhere else, somewhere further South, somewhere I had never been. Not the deep South, and not Pennsylvania. A place where there were still miles of undeveloped country, and rivers and lakes. My hair was long and blond, as it was at the time, and I was beginning to feel a bit heated from the sun on my head. Then something began to change; slowly I felt myself moving from myself. I don't have the words to describe it properly. I was moving from the driver's seat into the passenger seat, but I was still in the driver's seat. As if I were split into two beings. Two physical manifestations of my Self. I did not initiate it, it was something that just happened, in the dream. I could feel the transformation happen. It was not physically painful, but it did feel like a separation. Then I was in the passenger seat, and the person driving was, for lack of a better description, a male opposite of me. His hair was long and blond as well, sun bleached, and he had darker eyelashes and eyebrows. He smiled, I smiled, and all was still sunny and beautiful, the day was even more magnificent than before. All was as it should be.
"All shall be well, and all shall be well, and all manner of things shall be well." ~Julian of Norwich 

And we drove down that country road until I awoke.

I'm still waiting to find out.
I do love a good mystery.
