What a great way to explain it ;

I know exactly how you feel. I guess it is how differant minds work.

Are you familiar with (HI), hynagogic imagagery? I don't believe this was mentioned.
While going to sleep relax and close your eyes, but try to maintain some awareness. HI does not really take all that much concentration. It manifests itself. All you have to do is maintain a state of awarness until it leads you into a lucid dream.
Even if HI does not produce an LD it can be a remarkable tool for creativity and problems.
