Dreams and dilemma

Sometimes i will still get this kind of dream which i can't even explain in words. Words are of course one of the most essential and yet powerful to even end one's life...Anyway, why is this dream still running in my head. Making the brain to think of things that should not be in place anymore. So wish that peace can be fulfilled easily and no more hatred. Life would be so wonderful to see happiness scattered all over the place. Losing a friend is something that cannot be accepted just because of some uncleared issue.......
