Some dreams are literal or nearly so. Sometimes riding a roller coast is just riding a roller coaster. Some dreams, if you take a symbolic and analytical approach, mean more and say more than the action they depict. That roller coaster might be the story of your day or your life.
The rarest kind are wholly, or at least momentarily, conceptual and intellectual. That is, they are like reading a text or listening to a lecture, wherein an item is dictated or a point is announced.
Last night, a dream asked me to play a word game, to relate two words. It wasn’t quite a request, it was more like a reveal, as in “Look, don’t you see?”
The words were Freud and Freund (the German word for friend). I did not take this to mean that Freud is my friend. I took it to mean that analysis and investigation, which Freud is famous or infamous for, is/can be/may be near the heart of friendship. Friends may not want this or like this, we may not want to do this or complicate the joyful simplicity of a relationship, but it does happen.
Of course, Freud might find the dream and my interpretation of it…interesting. He might expect me to delve more deeply into why he made it into the dream at all, even if only as a name, and why in my dream I was playing word games instead of, say, riding a roller coaster or something equally thrilling. But then, I might ask him, as my freund, to kindly shut up and let me get back to sleep.
