I have a dream where I am with my family when suddenly, the ground begins to shake and rumble. We all start running. There is an alien invasion, and the aliens are these huge, metal spheres that roll over the Earth and destroy whatever is in their path. They don't exactly chase humans, but they do roll through more populated areas. My family runs and runs and runs. We head towards the coastal cliffs. We run through scaffolding of the side of the cliff, that presumably the aliens would not attack. We keep going, the thing rolls by and keeps rolling.
We meet up with some other people and go into this beautiful, coastal house with our community. Under the house, the group has built an extensive network of underground tunnels, with windows that open up in the cliff so that we can get light. You might not even know you're underground. We wait in the house until we hear that distant rumbling, and then run downstairs to the underground portion. The thing rolls over the house, destroying it, but we are all safe underground.
There is no way we can figure out to destroy the things yet, as they are extremely tough, metal spheres and we Earthlings don't know their weakness yet--but there is always a weakness.
We start hanging out in the beautiful underground house.
