If you're looking for a serious book about lucid dreaming, this isn't it. The authors included a few tips they learned from legitimate dream researchers, such as Stephen LaBerge. Unfortunately, most of this book is pure fluff, concluding with instructions on how to use lucid dreaming to promote ESP and out-of-body experiences. Oh, PLEASE! I'm surprised the authors didn't suggest putting aluminum foil on your head and sleeping under a pyramid.If you're serious about lucid dreaming, pick up a book written by legitimate dream or sleep researchers who know what they're talking about.BTW, I've been accused by some of working for Stephen LaBerge. Although I am aware of his work, I do not work for him nor with him. In fact, I've never even met the man. I'm just a regular guy who bought this book and was VERY disappointed.
