That's a good question, DS. I'll have to think about that.
Okay, dreams. I once had a dream in which, while I wasn't a soldier, I was in a trench on one side of a battlefield, a la First World War. I leaned forward on the parapet, and three persons on the other side rose up, as if to yield. I ran back to my post, where a general officer was standing, as if to reprimand me. Instead, he held out to me a camera. I was not to be a combatant, but a witness. On the parapet stood a woman, who sang one word, and the word was "glaube," which in German means faith, to have faith, or to believe. It was all very striking and colorful, a true "big" dream. I have them, on occasion. Anyway, this was before I gained knowledge of one of my ancestors, whose existence was uncannily accurately depicted in this dream. Are you familiar with the work of Carl Jung, his psychology of the unconscious?
