If you work in an office, then dreaming of your work place holds important meaning for you. If you dream that your office is strange and unfamiliar, it means that you are not correctly placed in your niche. In your waking life, you’re doing work that does not suit your natural abilities. That is why your dream shows you doing work that is unfamiliar to your talents. If your dream includes colleagues, than your brain is trying to tell you to pay attention to them. Your dream portrays your colleagues in the same light as they appear in waking life. So if your dream images of colleagues are bad, then in waking life, they are also bad, because dreams only continue the same themes as waking life.
