In the mysterious dream world, to dream of parting means the opposite. You will be meeting that person again. In some cultures, when you say goodbye for more than one occasion, it has bad meanings. The first goodbye may be a casual one but the second farewell may imply a parting forever.
You know how some people watch their loved ones walk through the departure hall until they disappear from sight? If you dream of this kind of scene, it means you might never see that person again. It could be a split in relationship, a long distance move, or some other situation.
