Interestig theory, but I feel most people experience lucid dreaming because of a personal mentality, and less so with physical, even the brain. It might not necessarily be your age's logic center development working against it, but more so the strength of your gut feelings, because they make you very impatient. Patience is definitely a large part of becoming lucid, because if you're impatient and you fail to get lucid, it will annoy you and possibly make you try less subconsciously.
