You are either lucid, or you are not. (You were). The only thing that can and is different is your level of awareness.

If you lucid with little awareness, first seconds may be clear and focused and you do an RC and you stabilize and do what you wanna do. But dream may soon become fuzzy, you will most likely just follow the plot, you don't have presence of mind to RC and stabilize continuously to keep yourself in the dream, and dream can soon turn into regular dream (FA is just that), because you forget that you are dreaming.

With higher awareness, you are able to keep stabilizing and reminding yourself that you are in a dream, or even stop stabillizing, because dream is vivid and focused and stable.
