If you are a Joseph Campbell fan like myself then you may want to visit the new rebuilt web site. You will find many resources not only to do with mythology but also dreams. Here is a bit of wisdom about dreams found at the site that provides insights to that wisdom.
"...Since the dreamer and his dream are the same, the subject-object opposition falls: the visions are of his own motivating powers; their personifications are his gods—or, if improperly served, disdained, or disregarded, become his fiends. Furthermore, since the powers of nature in this dreamer, in that dreamer, and in the macrocosm of nature itself, are the same, only differently inflected, the powers personified in a dream are those that move the world. All the gods are within: within you -- within the world." --Joseph Campbell, Creative Mythology
The above statement is a truth when applied o dreams. We are a macrocosm of nature itself. All Gods are within.
Campbell is an excellent primer for anyone interested in Jungian psyche and dreams. I know from experience.
