Think about the word Lucidity, it implies much more than lucid dreaming. Lucidity is clarity, clear thinking, clear expression. Lucidity is understanding and being completely present in the moment. Lucidity is not just for dreaming, lucidity is the main goal of meditation of any sort because it makes you mindful of everything around you and within you.

This is the strongest possible tool you can develop, besides recall, to further your lucid dreaming.
