listen. if you want to know if a dream was a lucid dream or not, ask yourself this simple question. "while in the dream did I know for a fact that I was dreaming?" lucid dreaming is simply that, knowing you are dreaming while in a dream. it doesn't matter how long or how short it was. as long as you knew it was a dream, then it was a lucid dream. otherwise, it wasn't. if you knew it was a dream but then you got caught up in the dream and forgot that it was a dream, it was still a lucid dream at one point, just very short. if you were in a dream and you thought that it might be a dream, but you didn't know, then it was not a lucid dream. hope I cleared that up for you.
