Hm. I can't really remember when I first heard it. I believe it must have been from my English teacher in high school actually. Never really quite understood what it was, but she and I were close, and I used to tell her my dreams. She told me about lucid al right.

You want to understand the rules of Lucid?
Well, first of all, I'd say there really are no RULES, but rather guidelines. "There are many ways to Rome"... It's good to know the different techniques, but I think you'll find it easier to apply them to your own dreaming situation and control when you're able to just follow your own ways, with the guidelines in the back of your head. Rather then something you feel you MUST follow.

I hope you'll get the wonderful experience of Lucid dreaming - it's quite astonishing.
