What can Lucid Dreaming tell us about consciousness?

http://www.scienceandnonduality.com/ Maurizio Benazzo(SAND co-founder) in conversation with Stephen LaBerge. Stephen LaBerge is the first scientist to empirically prove the existence of lucid dreaming. His work has developed this technique into a powerful tool for studying mind-body relationships in the dream state, and he has demonstrated the potential for lucid dreaming in the fields of psychotherapy and psychosomatic medicine. His books Lucid Dreaming, Exploring the World of Lucid Dreaming, and Conscious Mind, Sleeping Brain, have received enormous popular interest. He is the founder of The Lucidity Institute an organization that promotes research into lucid dreaming, and offers courses on how to achieve a lucid dream. lucidity.com
