WELCOME SCOTT!!!!

It is completely comprehensible for you to be afraid that you wouldn't wake up when you became lucid. Now that you know what LDing is, you know you don't have do be afraid of it, but rather embrace it. Control, just like Seeker said, comes with belief. To quote the matrix, you must "Free your mind", understand that it isn't real and therefore you can effect it as you wish. If you cannot control anything(unlikely, yet possible) take joy in just admiring the reality of it all, perhaps talking to dream people and exploring your environment. You must remember that nothing can really harm you, and thus if you are in a nightmare you can run from it, face it, or just try and talk it out...
