We are used to the modern proverb "it's all screwed up" as a metaphor for situations and relationships that fail to meet our expectations. Dreams of this nature often reflect our verbalization of people or things that fail to fulfill our needs. How many disfigured people or objects you encounter in your dream is an indication of what facets of your life are not meeting your expectations. Can you ascertain how the object or person came to be disfigured?
Does the disfigured object continue to work, or does the disfigured person seem unaware of what you are seeing?
