ok guys, just 2 quick questions concerning FILD's

1. How do you guys keep concentrated on moving your fingers becuase i lose concentration on that as pect pretty easily :S

2. I think too much about how i will know if i am in a dream so i non-intentionally keep myself awake because even when concentrating on my fingers, im wondering when the hell i should do a RC to see if im in a dream or reality.

any helpful responses would be much appreciated

cheers xD
