The Short Answer
In order to go into sleep your brain activity has to slow, if you've got too many thoughts going on, keep opening your eyes, moving, etc, you're sending conflicting signals to your brain. Your brain waits for cues to go into "standby" and by doing these things, you're confusing it. Aches can do this too, since they're keeping your nervous system active. So typically, someone who can clear their mind easily, and doesn't have any sore body parts, can go to sleep rather quick simply by laying down and closing their eyes. Someone who has a lot on their mind or has a restless leg, etc, might not be so lucky.
