The point of the overall meditative path is to have Wakefulness (or Consciousness as Such) transcend and include all state-realms, so it ceases to "black out" or "forget" various changes of state (such as dreaming and deep sleep), and instead recognizes a "constant Consciousness" or ever-present nondual Awareness, the union (and transcendence) of individual finite self and infinite Spirit.
