This from Wikipedia article on Dream Yoga http://en.wikipedia.org/wiki/Dream_yoga
"Tibetan Dream Yoga is described by Evans-Wentz in his book Tibetan Yoga and Secret Doctrines (London: Oxford University Press, 1935) as one of the six subtypes of yoga elaborated by the Tibetan guru Marpa and passed down by his disciple Milarepa. The author describes six stages of dream yoga. In the first stage, the dreamer is told to become lucid in the dream. In the second stage, the dreamer is instructed to overcome all fear of the contents of the dream so there is the realization that nothing in the dream can cause harm. For instance, the lucid dreamer should put out fire with his hands and realize fire cannot burn him in the dream. Next the dreamer should contemplate how all phenomena both in the dream and in waking life are similar because they change, and that life is illusory in both states because of this constant change. Both the objects in the dream and objects in the world in the Buddhist worldview are therefore empty and have no substantial nature. This is the stage of contemplating the dream as maya, and equating this sense of maya with everyday experience in the external world. Next, The dreamer should realize that he or she has control of the dream by changing big objects into small ones, heavy objects into light ones, and many objects into one object."
I particularly noticed the goal of eliminating all fear in the dream state.
"The primary aim and foundation of dream practice is to realize during a dream that one is dreaming. Once lucidity has been established the applications are limitless. One can then dream with lucidity and do all sorts of things, such as: practice sadhana; receive initiations, empowerments and transmissions; go to different places, planes and lokas, communicate with yidam; dialogue with sentient beings, creatures and people such as guru; fly; shapeshift, etc. It is also possible to do different yogic practices while dreaming (usually such yogic practices one does in waking state though the product and fruit of sadhana is greatly accelerated due to the learning, play and practice context). In this way the yogi can have a very strong experience and with this comes understanding of the dream-like nature of daily life. This is very relevant to diminishing attachments, because they are based on strong beliefs that life's perceptions and objects are real and, as a consequence, important. Dream yoga mastery not only assists in the complete realisation of shunyata, but also in the lila of Mahamaya. When one realises and embodies the Shunyata Doctrine of Buddha Shakyamuni and Nargajuna amongst others forded by Dream Yoga and other advanced sadhana, complete realisation is imminent and elementary."
Hmm. Sounds like what we think of as being operative in NPMR.
And, perhaps, most applicable to MBT:
"Namkhai Norbu gives advice, that the realization that the life is only a big dream can help us finally liberate ourselves from the chains of emotions, attachments, and ego and then we have the possibility of ultimately becoming enlightened."
There are NUMEROUS links in this article to complementary subjects which are all fascinating but I will leave that up to the reader to wade through. This is a fascinating subject and I found many parallels to MBT concepts.
