There is a whole Dream Yoga used by some Tibetan monks. Tenzin Wangyal Rinpoche wrote a book about it. Dream Yoga involves visualizations and its aim is to achive a state of conscious state of mind without dreams, while asleep. From this point, a practicioner is trying to liberate, so called enlightment. It's interesting that they believe that our dreams aren't different from our day-time reality.
