Van Dusen points out that, if nothing else, this is probably the only full recounting of one man's dreams from so many years ago. What is particularly fascinating about Journal of Dreams is not so much Swedenborg's night visions, for most people's dreams are so personal as to be almost meaningless. Rather, it is the editor's excellent understanding of the dream process. In fact, Van Dusen's Introduction is one of the best primers extant on how dreams occur, what they mean for the individual, and how one should look at them. Once you get used to the peculiar language of dreams they become a personal guidance system with a superior overview of the nature of one's own life.
Dreams are valuable guidance system.
Should I be in error with Swedenborg's dreams, I would expect my own personal guidance system to tell me so. I need my own dreams to monitor my understanding of his. This might surprise you. But when you are working on something, especially when it is close to your life concerns, your dreams will tell you how well you are doing. As some of the rest of us have discovered over the years, dreams are a feedback system, and a very sensible one.
