It is the product is 2 CD's. On each CD four titles are available. I like most the "Meditation for the hypnagogic falling asleep" and the "self-hypnosis". The other tracks I did not really need it. Since Charley tells a little about lucid dreaming; and there are still musical tracks.
I would love to even attend a seminar with him, because so far convince me his book and this CD!
Buy recommendation!
