Dreaming of a coworker indicates you are attracted to the qualities that your dream partner possesses. There is something about them that you admire from afar, but cannot tell them in person. The dream allows you to act out the desire towards a better working relationship with the coworker. It does not represent you wanting know them more intimately.
Seeing a coworker in your dream means enjoying the forbidden love of fraternizing with people in the same company. You both may hit it off through flirtations at office outings and continue to hide the affection in front of others.
Unfortunately this will not last as too much tension will arise from being found out and the initial feelings could slowly disappear.
i had a dream that my brother came into the store i work at and my coworker very obviously had a crush on him, got his number, than she was acting like a little kid at how excited she was to get a text from him.
