RC's failing, Lucid Limit?

[Zodionic]

I had a very long dream last night, I't was vivid, actionpacked and I had great recall when I woke up, basicly it would have made a perfect lucid dream, if I had became lucid. Heres my problem, In the dream I was in a libary, I asked for a book about lucid dreaming, I got the book and sat down and a girl asked me what I was reading about, I started explaining about lucid dreaming and showed her 3 reality checks. I didnt become lucid, and this fustrates me. This happens to me all the time, I remember doing reality checks in my dreams and just continuing on in the dream and not being lucid. Now, the night before I became lucid, about half way through my dream and I didnt even need to reality check, I just realised that I was dreaming, this is how I usualy become lucid. I have 1 or 2 lucids a week, and manage to wild about once every 2 weeks, but in my dreams I hardly ever become lucid through reality checking anymore, I do a reality check once I become lucid just to confirm its a dream. So I think maybe reality checking isnt working for me because I am already having lucid dreams at my own pace, and maybe my mind is stoping me from becoming lucid more often than I already am. Droes anyone know if this can happen? maby theres a limit to the amount of lucid dreams your brain can let you have

I would assume (for the library one anyway) that the reason you didn't become lucid had something to do with the fact that you weren't doing the RCs to see if you were dreaming. You were just doing them passively. It's not the action, but the though process that's important.

I did the same thing last night. I got into a fight with my dad for doing something stupid, then shouted "It doesn't matter anyway, it's just a dream!". I then did a double take on that statement and became lucid. So yes, on some level I would agree that you always know when you're dreaming. Doing an RC just kicks in your consciousness.
