i can really recomend this book http://www.amazon.com/Tibetan-Yogas...5916758?ie=UTF8&s=books&qid=1181468324&sr=8-1 Dream yoga is rather similar to the art of "lucid dreaming". Becoming aware of your dreams, in your dreams. And using the dreams to practise your spiritual side (not just have erotic dreams and such, as appealing as that may seem ^^)
