It's possible that your RCs failing has something to do with you not putting enough or right emotions into practicing them during day.

You have to believe they will work when you RC in daytime. You have to believe you are in a dream. If you don't, you will not believe that in your dream either.

And adding awareness training to your RCs is a good idea.
