In my dream, I looked at my hands and noted that the word 'dream?' had disappeared from my palm. I also wasn't wearing my glasses in the second lucid dream, but my vision was perfectly clear-- in real life, my vision starts to blur about four feet from my face, so that was a major sign.
Good luck with your phoenix-spotting! I'd sincerely recommend the wake-back-to-bed approach for inducing lucid dreams.
