There have been other great scientific civilizations on earth that have vanished. Some could now be thought of as "earth gods" who care about our well being. Some used sound for healing, for wars, and for moving object of great size and weight. In dreams we try out various probabilities to help us decide which one we want to bring into our waking awareness. The dream reality is real, and some personalities we have been close to for a long time in the dream reality might be strangers to us in waking reality. The connections among us, our probable selves, past and future selves, incarnational selves, and entities in other realities we aren't even aware of, are complex ... and we affect one another. Your slightest thought can give birth to a flower in another reality, and the thought unspoken has a sound we do not hear.
