Judging from this post and your signature, I understand that you define awareness and our being, our mental existence, as the nature of mind? And by saying it does not change during our lives, you mean that even though not all of us have learned to access it while asleep, it is actually accesible in any state? And then your third hypothesis states that learning how to access this awareness, this mental existence and presence, while asleep, will lead to lucidity?

Please tell me whether I have understood that correctly. If I have, I support your hypotheses and agree on your drawn conclusion. However, I do not yet see how this differs from the ideologies behind both modern-day awareness techniques and ancient meditation. Would you care to explain further?
