If you realized that you were dreaming even if the dream ended right away.. I would still count that as a lucid dream (albeit a very short lived one). You still had a moment of lucidity.
Did the dream go black the second you realized you were dreaming? If so, that's still a direct result of your recognizing the lucid dream state.
Honestly it would be a "personal" decision as to whether you would count it as a lucid dream or not.
Either way.. you got a taste of lucidity and it's an experience to build on and learn from. ;)
