To dream of a van (work or delivery) represents your decision making ability or self-control that’s interesting other people in what you are thinking. A reflection of life is providing you or someone else with their needs, wishes, or fears. Choices that lead to “getting what you asked for.”
A direction in life you are headed that is easy influencing others or where other people’s choices are totally in sync with your wishes.
Negatively, a van may people or bad experiences that seem to do exactly what you don’t want. Positively, a van may reflect coincidences or people you know making choices that benefit you.
