What does it mean when you dream somebody tells you they are gettin divorced?

As a basic principle, dreams are about the dreamer. So the person getting divorced in this dream would be the dreamer. However, "divorce" need not mean an actual break up of the dreamer's marriage, but a separation or severing of some significant commitment. It could be the marriage or it could be a partnership, a friendship, a job contract or even membership to some organization. Other details in the dream should provide hints as to the identity and context of this separation.
