I have had the same dream about four times throughout my life. In the dream I fall through the floor and find myself in a cement room with no doors or any way of escape. I turn around several times untill I notice a door that wasnt there befor I go through it and it desends. Finally I reacha dead end. The ceiling is up veary high. There is a ladder but It only goes halfway down well out of my reach. I go back up and notice a second door right next to the other I go through that one and find the door slightly smaller then me I go through and eather wake up or dream about something else. Does anyone know what it means?
