KNOW YOUR DREAMSIGNS! simple, huh?

My biggest dreamsign is when I look in the sky I can see very strange things (star nebulas, comets, ufos, ect). Because of this dreamsign I incorporate it into a RC mechanism. When I look at the sky in the waking world (a habit of mine) I note whether or not I see anything odd or unusual. In my experience this has realy increased the frequency of lucid dreams. Maybe I am lucky because this is a dreamsign that I can convert into an RC reminder but I would imagine that anyone could incorporate this same technique with thier own personal dreamsign.
