Highways in Tornadoes

Date: 5/30/2017

I was sitting in one of my old daycare classrooms. It was pouring outside, and the building was sitting under the highway, and it was at least a fourth of a mile above the ground. The teacher was babbling on about something when a siren was heard. Being the curious guy that I am, I immediately left the room and ran outside. There was this patio that led to a sudden drop (as the building was in the sky). I looked up, and noticed three tornadoes coming closer to me. They were huge and towered over the highways. The last thing I remember from the dream is a tornado grabbing a chunk of the highway and flinging it directly at me. Just before the moment of impact, I awoke.
