Yea, practice and awareness are key. The more you question things in waking life, the more likely you are to question them in the Dreamscape as well. All in good time my friend. Just a suggestion, but I would try a different kind of RC other than the palm trick. For instance, try to remember how you got to be where you are in the Dream. Dreams jump around so your memory will not be linear when you are Dreaming and when you realize this, voila, Lucid Dream.
