Query: Meh...

I only read the book about half way through. I would not recommend it for anyone with just interest in the subject of lucid dreaming. Some of the tasks described in the book are just impractical. About a solid 90% of what is given in this book is not necessary in order to lucid dream. Only get this if you want a quick supplement to something else way more in depth on the topic and/or techniques.
