I learned a similar trick from an old LW post. You focus on the static in your visual field. If it starts to resolve into random seeming images, that is the beginning of hypnogagia, and if it starts to resolve into even more concrete imagery you are very close to sleep. Try to keep focusing on it, eventually you will fall asleep. This generally works for me.
