Obviously, when we awaken from a nonlucid dream about a jerk, the reality of that situation vanishes like smoke. Since the dreamed person was nonexistent, the label "jerk" was also imaginary. When we view people so narrowly, whether in dreams or waking reality, we invariably decontextualize -- placing absolute labels where no absolutes exist. The true context for all persons and objects is interdependence. The condition of dreaming, whether it be in the night or in daytime, subsumes a form of ignorance where we can easily misconstrue appearances. Dreaming invites us to become deluded. We can either go with the flow or wake up -- check it right there and realize that although the object as we perceive it appears to be real from its own side, that appearance is illusory.In terms of our normal mode of understanding reality, analyzing phenomena in this way turns everything on its head. But even if we are, at this point, thoroughly convinced that "all phenomena are nonexistent," our present understanding is only conceptual. In Tibetan Buddhism, conceptual understanding is likened to a patch on clothing that sooner or later falls away. It is the habituation of the practice of daytime dream yoga that will allow our understanding to deepen and prepare us for an awakening that encompasses both the day and the night. To quote Chagdud Tulku Rinpoche -- one of the most prominent Tibetan lamas who taught in the West -- "All dream yoga is based on the one-pointedness one can maintain on the illusoriness of experience by day."
