I think of freedom when I see this one. Imagine you are stuck in your house bound to a wheel chair and all you want is the freedom to leave when you want, by yourself, without any hinderances or assistance. I could imagine staring at the ceiling praying for it to come crashing down and to be able to fly up out of my chair away. This house is all old and dilapitated but you can see where nature is coming in now that there is a way, with the ceiling being in a big pile on the floor, and it is green and fresh and full of life. I imagine the wishes of the occupant of the wheelchair finally brought the ceiling down and gave them wings.
