Thread: Strong man and fragile girl

For as long as I can remember (I'm 13 now) I have had recurring themes in some of my dreams. The dreams don't come at any set intervals. In these dreams there is always a big, tall, strong, dark man and I always associate him with force and with strong machines (tanks, cranes, etc.) and there's always a small, fragile, light girl. I always associate her with a pale, powder blue, and with a little flower. The flower feels as if you hit it slightly, it could just break. There is never a background in these dreams, it's all white. No ground (just white) no walls (just white) no ceiling (just white).
The man sometimes has his friends in the dream, but they're just a crowd of people, no individuals.
The man always tries to somehow destroy the world (using explosives) and the girl is always the last to go. I forget if she actually dies in the dreams, or if I wake up before she dies.
It's very hard to explain in words, because a lot of these dreams are like feelings. There is always a weird mixture coming from the forcefulness of the man and the fragile-ness of the girl. (like they're clashing or something, so hard to explain).

So, what do these dreams mean? Does anyone know? Is there a reason I always get them?
