I dreamt the human race was destroyed

[BlissBaby13]

About a week ago, I dreamt I was on a walk with family through a series of meadows and glades. I laid down on the grass, withdrew a bow and arrow, and aimed it at a nearby oak tree. I loosed it and it stopped in mid-air and spun around, driving into the ground and into my grandmother's shin.
As she cried out in pain, and I gasped and tried to help her, my vision zoomed out incredibly rapidly and I saw the Earth from above; it was stunning. I had a moment where I completely forgot all I knew about myself and the earth and all I'd learnt in my human body, and I just watched in awe from my place in the middle of nothingness. Then, on the earths face, I saw spinning white vortexes begin to appear; they radiated divine light. I came back to my place in the meadow quickly to see my grandmother remove the arrow from her leg. Layered across that image, I saw the earths chakras once more. A screaming wind began to pick up, and my family quickly tried to usher me away into the cover of a nearby willow tree, but I just stood in the middle of the grass and stared at the sky, almost expectantly. I heard a voice inside my head, different and louder to the one I hear in my waking hours, telling me the earths chakras were somehow creating and spreading peace across the earth, but also with the intent of destruction. I said I didn't understand, and then I saw foreign predators begin to flood the meadow; every kind of animal imaginable. I saw the hills begin to carve themselves into the faces and bodies of animals, and the creatures were beginning to round upon any human beings within the area. I saw the image of the earth layered over my actual surroundings once more, and saw nature beginning to reclaim the earth and crushing man-made buildings, predators devouring human beings. I just stood there, not afraid, and the animals didn't so much as look at me or my family.
I don't think it was prophetic, but what do you guys think it means?
