I look at my hands, count my fingers, and sometimes pinch my nose, and ask myself if Im dreaming and were was the last place I was at.
Theres no point on making a reality check if your not really checking reality. If you look at your hands many times a day, it might end been an automatic movement, making yhe rc fail during the dream. Instead, if you really questioon yourself if your dreaming, you will do the same during the dream, making Lucidity much more probable.
