Spot on. There is no external authority on meaning, especially the meaning of dreams which are your own personal Waring Blender on reality and mean what you decide they do. It is possible, surely, to invest a dream or any other creative act with meaning from a level of high creative energy, and then drop down to a much lowerr level of energy to experience it. That way you can enjoy the mystical mysteriousness of it all, and ponder indefinitely. If you go in for that kind of thing.
