Hi nia02, it takes time for daytime practice and heightened daytime awareness to manifest into your dreams. While you're adding in RCs and heightened self-awareness to your waking live, also work on dream recall and dream journaling -- this helps a lot. One of the foundations of lucid dreams is great dream recall and frequently having very vivid dreams. Be patient and keep up the practice. How's your dream recall?

Another recommendation is not to formally assert "I'm not dreaming" to yourself, but rather frame the thought as "well I'll definitely be dreaming later."

For your dream signs that only occur in dreams, you can still visualize these scenarios while awake, and add in the realization that "I'm dreaming!". The more you set up this association, the more likely it is to occur in dreams.

It's important to keep a positive attitude toward dreams and dreaming, while you're working towards your first lucid dream. Celebrate and be thankful for all your dreams, including (and especially) the non-lucid ones, this will IMO help to bring the lucids sooner.
