Dreaming about LDing, or Very short LD?

Well, last night was cool. A HUGE stepping stone in m progress ( I hope ).

I was dreaming that I was outside and it started raining, but the rain wasn't water drops, it was nails, and the nails were sticking into the ground. (Now, this is where Im not sure ) In the dream, I was like " wait a sec, it doesn't rain nails.. I'm dreaming ", and did a " reality check". The only problem is I think it was my DREAMING mind that did the RC. So, I think I dreamed about recognizing a sign, and dreamed about doing a RC without REALLY doing one.

Anyways, is this a good sign? To me I feel I'm getting closer, and I feel the stuff Im doing to help Lucid Dreaming stay in my mind is working, because if Im dreaming about LDing, then its obviously in my mind somewhere lol.

any opinions on this? Thanks guys
