Of the 60 pages in this odd little pamphlet, fewer than 8 deal directly with the topic of lucid dreaming. The balance of the "book" is a rambling essay touching on sleep, insomnia, history of dreams, dream interpretation, and nightmares. Not much "advanced thinking" either; the writing is sophomoric, at best.
For less than half the price of this piece get a copy of LaBerge's "Exploring the World of Lucid Dreaming", a veritable encyclopedia of lucid dreaming by comparison.
