Importance of dreams is not in using - importance is in having. You think dreams must mean something real, that fantasy bad for the soul. All wrong, all wrong. Fantasy just as important as reality. Reality is feeding body - finding food for keep alive. Fantasy feeds spirit. Soul need food same as body, and dreams, philosophies, stories, creations, all food for spirit, see?
Wouldn't it be nice, for once, to find a world which was at peace with itself. No matter how always those few wanted more than others. Those not satisfied with running their own lives but wishing to have power over the lives of the others. Greedy people. Greedy for wealth, or power or both.
