The floor symbolizes how much you are grounded to your life and the way you are able to move one. The floor could also signify your relationships with yourself if you are floating or feel grounded enough in order to understand who you are. If you are brushing the floor or cleaning it in any other way, then it shows that you are looking after your life and take care of many things no matter how hard it is to do them. The floor that is distorted signifies that you are not grounded enough, you took the turn from your path, and therefore you do not feel stable anymore.
