Thread: Would it make a difference?

I don't think there are any significant differences in brain waves between normal and lucid dreams, but your eyes will move like they are in the dream. So, a dreamer could decide an eye movement patern to signal lucidity like moving the eyes left and right 10 times. This is how people have proved that lucid dreaming exists.

I've heard they can detect which areas of your brain are active when you think of say, a banana. So what they could do is have you think of a banana while awake, then record the pattern. Then when you're lucid, start thinking of bananas, and there you have proof.
