yes, looking at the hands in the dream state is also a good way to get lucid in the dream. i remember learning this from Castaneda's "The Art of Dreaming". this is one of the dream signals i use. for example, when i look at my hands in the dream i'll notice its shapes-shifting features, sometimes the colors change. the real challenge, of course, is to *remember* to look at them in the dream, let alone touch objects and feel the sensations
