I had a very similar experience the other night. In one dream I seemed to realize that I was dreaming, looked at my hands to try to gain control, and lost lucidity THREE TIMES within a few minutes (!), and like you said it seemed like a dream about a lucid dream. Kinda hard to explain... It was pretty strange and frustrating considering that I had three opportunities to have an LD but for some reason it didn't happen.
Maybe it's just that your sense of awareness was right at the threshold needed for a decent LD.
