It's for relaxation and meditation. There is no one talking in the first CD. I don't know about the other CD's but I don't think anyone talks in them. It has something called a sound matrix that is supposed to help get into deep states of relaxation. You are supposed to listen to the first CD for 30 days before going to the second one. It doesn't say anything about lucid dreaming. Just relaxation and meditation. But I think the deep relaxation would help with WILD.
