A lucid dream is defined only as a dream in which you know you are dreaming. Because of this loose definition, lucid dreams can be completely different from one another in terms of how vivid they are, how much control you have, and how clearly you're able to think. What you experienced was lucid, it just wasn't of the same quality as the first lucid you had.

I would say that most of my lucids are not very vivid, and I do not think clearly or have much control. But I do know that I'm dreaming which makes these lucid.
