To dream of repairing something represents recovery, restoration, or some area of your life that has upset you. Disappointments being corrected. Relationship problems needing to be reconciled. Setbacks you are working on resolving.
Alternatively, repairs in a situation may reflect your awareness of mistakes that you don't want to repeat in your life. Damage to something in a dream may reflect feelings about regret about mistakes you made, excessive behavior that has embarrassed you, or losing function in some area of your life.
Negatively, repairs in a dream may reflect your awareness of fixing a negative aspect of your life. Bad relationships you are reconciling. Returning to bad habits after first trying to move on from them. Expertise in dishonest or criminal behavior that is being used to restore a dishonest situation. Feeling that a problem situation will never end. Enduring other people making your life difficult.
The object being repaired symbolizes the area in your life that is being are worked on.
Example: A man dreamed of repairing a house. In waking life he was trying to fix a relationship that was causing him a lot of depression.
