Ever since I have been reading and learning about Lucid Dreaming, the thought that seems to be paramount in my mind is the sense that ALL of this is a dream. 21st Century physics teaches us that all matter is basically empty space at the quantum level, i.e. nothing there...an illusion. I think my first taste of the LD this morning is only going to whet my hunger for more and deeper journeys into this illusory realm we are all sharing. All that we see or seem is but a Dream within a Dream.
