Whether born with it or not, I think it is a mindset that is most important. And once you set your mind to it, your dreams will be different and memorable. Even if non lucid, once you recall your dreams extremely well it is like a second life and lucidity is bound to happen. Perhaps some of us always knew that our dreams were important and worth remembering since memory began in the first place. But anyone can start remembering their dreams if they simply try and that is the key to not only lucid dreaming but knowing yourself subconsciously. Whether lucid or not, the dream realm is always exciting! I'm surprised dream conversations are not more 'main stream'.
If we all lucid dreamed this world would be a better place.
