Have you had a couple LD's before you've had the spontaneous ones?

It might be that you're particularily adept now at noting the feeling of a dream, how it's different from reality. You know, when you're in a dream, even if it's incredibly realistic there that slight sense in the back of your mind that you know it's not real.

There was a topic earlier about a few people who no longer did RC's, they could tell that they were in a dream, now lucid, because it did not feel like reality does.
