As long as there was a moment where you knew you were dreaming, then it was lucid. There are many times when, aftering becoming lucid, it seems kinda light and the realization doesnt really sink in, i.e. you still have some slight fears and hesitations about doing things even though you know it's a dream. But that's only because your awareness is not quite high in the dream. I suggest that when you become lucid, ask yourself logical questions like who you are, your age, your family's name, some simple math calculations. Then stabilize good luck
