Ya it all helps. I'm no guru but I've had a few LD's now and all that any of this does (RC's, DJ etc) is improve the chances that you will have a lucid dream so the more you do them... the higher your chances.

I have incredible dream recall for whatever reason but I might be able to help you out there... As you may or may not have noticed, sometimes when you write out say 1 that you remember, another dream might all of the sudden come to your head. The trick is coming to that cue that signals what that dream is... anyways that was written confusingly but point is... when you wake up, go through everything in your life really quickly (ie family, school etc), just an overview and I think you'll find it can really help.

Sometimes, for instance, I won't remember I single dream... and then after I try that technique, it will be enough to cue me to the fact that 'oh! my dream involved... my brother' and you can go from there. Try it out
