I've been looking in some books I have for info on the topic too..... no luck though..... while finding out the scientific reasons behind the colors and such would be nice.....mostly I just wanna learn the best way to use them to be lucid.....

Once lucid.... thinking about the fact that practicing things in my dreams will increase my abilities with those things in waking life is exciting..... course once I am lucid regularly I am probably going to want to do more out of this world crazy things...... maybe once that newness wears off I will spend my dreams fine tuning my skills in some areas... like guitar...
