This has happened at least once. I have gone into a dream almost knowing that I was dreaming. I did a Reality Check to confirm this (sticking my finger through my palm) and was certain that I was dreaming. I spun around and teleported a couple of times, but barely a few minutes into the dream, I found that it had distinctly low quality. I frequently reminded myself that I was dreaming, but that didn't help with the quality. I was left with a somewhat bittersweet feeling when I awoke; the joy of a lucid dream was combated with the low clarity and quality. I also discovered that (using a sleep pattern recorder) the dream had lasted over 40 minutes, despite being one of the first dreams of the night.

I also unearthed another issue-despite having flown a couple of times in non-lucid dreams, I could not fly in my lucid dreams. I attempted to soar the skies by jumping higher and higher, and as I neared the tops of the buildings, I touched the ground to make what may have been the final jump before flying, and instead ended up face-down on the ground. This is very frustrating for me >
