Navigator said, "What if the Hindus are correct and all of this is "Maya", Illusion? According to Hindu theology, and also "A Course in Miracles" we have never left our home in heaven. We are only dreaming a lucid dream of separation that never really happened. The concept of memories only becomes important if you believe that life is in the body. According to the mystic Joel Goldsmith, there is only one body and that body is immortal and eternal. This thing we have on earth that ages and dies, gets sick, and suffers all manner of distress is merely a "concept of body".
I would add to this that the dream becomes lucid only after waking up to what you really are; until then, the dream seems very real indeed. Just as when dreaming at night there exists the belief that it is real, this life we are living seems very real. When there comes an awakening within the night time dream, when the dream becomes lucid, the dream continues but there is no more investment in believing in it as real. Similarly, when one wakes up to what one really is (pure consciousness), the dream continues but it is now "lucid" - there is no more getting caught up in the dream itself because the "dream character" (ego) is directly seen to be illusory. This is the "liberation" that Buddha and other awakened ones have been pointing to.
There is only one "life" and You are it. That "life" is pure consciousness; how that life expresses itself is nearly infinite in nature. The forms of that expression come and go, and the 'you' that you believe yourself to be is just one of those forms. As the form changes and seemingly disappears, life, the real You, continues expressing. In this sense, the world as we see it is illusory because it comes and goes, but You as consciousness remain unaffected, unchanging, and eternal. There is no death, only the changing forms of the expression of pure consciousness/You. "Heaven", therefore, is all around you right now.
