Dream of building

I was at school. Then, there was a tornado so all the students had to go outside and get into these little cellars. However, there weren't enough for all the students so me and another student had to go sit in this building made of glass. The building had a chair in each corner which we hid behind. The other student peeped out the window and saw that the tornado was over and British soldiers were marching over a hill towards us. One of the British soldiers saw us and then came into the glass building and shot us. When they shot us, we turned into cans and they threw us into a tote full of other cans.
