okay, a while back, i read about a technique, something like this:

To help keep your mind from wandering, just move your pointer and middle finger up and down over and over again against the bed, and only concentrate on your 2 moving fingers. after about 15 or 20 mineuts pass, do a reality check. The finger movement should enter the dream.

Well i tried this, but, where im so bush concentrating on finger movement, i cannot fall asleep! i need some help or advice.
