Well it was a very nice but "intellectual" vision of lucid dreeming. There where some very good lucid dreamers in it like Line and Stefan LeBerge but I would not call it a guide. There was a philosphical question that if the consciousness has submerged out of the unconsciousness to make us survive better, and dreaming is the subconscious talking of the brain to let the brain cool off and recuperate, then what is the function of lucid dreaming? The awnser was a very nice one: to improve on daily challenges like sport.
