I dreamed that I was staying in a metal structure, similar to a tin shed that was very large. There was a container built in it to dump trash. I remember taking a bag of trash and dumping it into this container. Suddenly I could hear the trash falling way down somewhere. Before I knew it the whole tin structure I was standing in began to fall. I could hear and feel the structure cascading down deep into the earth as the velocity began to lift me into the air. Unable to retain my consciousness due to the sheer magnitude of the situation, I woke myself up. I also remember having a dream of living with some people in a survival shelter made from a silo.
