Dreams dictionary: Office
Dreams dictionary: Interpretation 1
To dream of your work office indicates that you cannot seem to leave your work at the office. You are overworked or have too much on your mind. Alternatively, an office symbolizes practicality, status, accomplishments and your place in the world. If the office in your dream is unfamiliar or strange, then it suggests that you are comparing yourself to someone else. You are measuring yourself against other's standards.
Dreams dictionary: Interpretation 2
To dream that you hold public office represents your acceptance for the consequences of your actions. You are taking responsibility for what you do.
Dreams dictionary: Miller Dream Interpretation
For a person to dream that he holds office, denotes that his aspirations will sometimes make him undertake dangerous paths, but his boldness will be rewarded with success. If he fails by any means to secure a desired office he will suffer keen disappointment in his affairs. To dream that you are turned out of office, signifies loss of valuables.
