Query: Easily the best book on Lucid Dreaming.

First, I must state that I want to give this book more around 4 1/2 stars, but I mine as well round up.If you are starting to become interrested in lucid dreaming, I HIGHLY recommend that you order or pick up this book. It has techniques for becoming lucid and tips for what to do when you're lucid. Along with that, the book has ways for lucid dreaming to further improve your life, beyond the aspect of just having fun.However, I wanted to give the book 4 1/2 stars for one reason and one reason only. Like other reviews that have stated this, this book totally is without the spirituality that is experienced during a lucid dream and LaBerge's theories on dreams are a solely based on Freud, which may or may not be a good thing, depending how you look at it.Overall, excellent book. If you're looking into lucid dreaming, read this book. Believe me, it will be an incredibly useful tool for you.
