Dream of children, screaming

Im on a different planet looking down on the earth. Im in this absolutely gorgeous place with green grass and flowers surrounding me but i can hear wailing and screaming in the distance. I have a deep feeling of hopelessness and dread. In the grass there are many sticks and in order to save the world i have to pick them all up and shove them into a huge cannon which is the only thing in the vast expanse of grass. As i do i can hear the wails and crys comming from earth getting louder. Mothers that know something is going to happen to their children and children crying out in terror. I try my best but I know I can't succeed. I sink to the ground sobbing and then I wake up with the sound of the crys ringing in my ears.
