Lucid Dreaming and Conscious Dreaming are one in the same. It is the awareness that you are in fact dreaming. In other words you are aware that what you are experiencing is occurring in a dream, while you are having the dream. Lucid dreaming allows you a particular amount of control that you do not have while dreaming normally.
This is a true metaphysical power, this power over your own dreams' actions and events. Instead of things being done to you, you are the star, and the writer, of the story, and you can use this power to help bring about great changes in your own waking life.
