I had a random thought while I was laying in bed last night, which comes down to this:

Your mindset is extremely important when it comes to lucids. If you believe something is not possible, you can't make it happen. Then I wondered, how do we know for sure that a lucid will fall apart if we become too excited about being lucid? What if that only happens because we have been told that that's what will happen and now we're expecting it, thereby creating a self-fulfilling prophecy? I remember reading about Stephen LaBerge coming up with a similar question, only it was about the idea that a dream would stop if you said your own name, if I remember correctly.

How do other people feel about this?
