The Tibetans have develloped a dream yoga based on the acient Tibetan shamanic Bön tradition and Buddhism. While being a Buddhist yoga the goal is Enlightment it is also supposed to give supernatural powers on the path.

For anyone who is interested I suggest the book

"The Tibetan yogas of dream and sleep" by Tenzin Wangyal Rinpoche.
