Hey, I have thought about this also. If lucid dreams feel as real as life itself couldnt you train yourself to handle situations good? Like if you were in the military and you had to learn to keep your cool but you hadnt been on a battlefield before. What if you went through the scenes over and over in your head and at first it would be scary. But after doing it hundreds of times you would become a freakin hero ont he battlefield... think it worx?
