Supposedly for the RCs you have to actually question whether you are awake or sleeping when you do them. That way your brain associations that curious feeling with the question and when something similar happens in a dream, it triggers lucidity. You could just be doing them without enough awareness. I dunno. You are supposed to come to a rational conclusion that you are not dreaming, instead of just saying the words.

Yes, I'll let you know if my techniques work, and I hope you become lucid soon. I'd be glad to help, but an experienced dreamer would probably be a better person to ask for now, until I've got some lucids under my belt.
