You need to practice doing RCs throughout the day, and when you do them, actually think about what you are doing. Really question your reality, think ; 'Could I actually be dreaming right now? If I were, what would it look like?' I like to listen to conversations, and ask myself, 'Is this a normal thing to talk about, or could I be dreaming?' Then once you do this, look around, take note of what looks normal etc, and then do your RC. This will make them have more meaning in the dream.
