In a dream, depression means the opposite. That is, joy, happiness and celebrations. However, if one sees his friends depressed in a dream, it means suffering in the same way when he is awake.
Family suffering
Depression in a dream also denotes illness or suffering caused by one's own family, or it can mean imposition, confiscation of business, cancellation of contract. It could also mean business stagnation. If all this were true while awake, then witnessing such depression in a dream could mean relief. Depression in a dream can mean either happiness or distress.
