What is the difference between a lucid dream and an OBE? I read in one book about lucid dreams that lucid dreaming is for the most part mimicked off of our fantasies and what our subconscious dreams up, so to speak; and that if a person has an OBE of "flying" through, or being in a various place in his astral body, that he's actually there, seeing everything as is - through his astral eyes. So, what's the essential difference between the two terms, and how much of this is really true?
