are you saying that you just don't RC in your dreams, or that you do and nothing changes? I'm guessing it's the first, if that is the case then just keep at it. Make sure you are doing plenty of RCs durig the day. And some advice: don't let it become routine, to where you are just going through the motions. You have to seriously question if you are dremaing or not. If you suspect you aren't, prove it to yourself. Case in point: last night when I was dreaming, at one point I became a little unsure of my situation. I did a few RCs, but I wasn't really thinking too hard about weather or not I was dreaming, resulting in the RCs failing and me remaining non-lucid

in other words, just keep at it and it will pay off eventually.
