I agree with gab and chase. It is best to try a less difficult technique when you are beginning. The FILD might not have worked because you had been sitting awake for a long period of time. You need to be relaxed. Or you might not have woken from REM. Also, it's best to just go back to sleep if you try to WILD/FILD twice and they don't work. The longer you try the harder it gets because you are more awake and are frustrated. You probably didn't remember any of your dreams after your attempt because it had disrupted your regular sleep pattern, but I can't tell you for sure. About the RCs, keep trying. I tried them on and off for more than a few months and my lucidity never came from an RC. But then they started working and it was definitely worth it. Also, try to avoid using the word 'fail' (unless you know it doesn't affect you, for some people it doesn't). By saying you 'failed' your lucid attempt, you are making it more difficult to succeed later.

Hope something in this helped. Good luck!
