If your dream is literal, then the people and images populating can be interpreted as themselves. But often in a symbolic dream, which reflects our inner thoughts and feelings, recognizable people and images are playing a role or are about something you need to figure out about yourself.

In symbolic dreams, PEOPLE, especially those close to us, are often an expression of a different aspect of ourselves or an expression of a characteristic of that person. For example if you dream of your father whom you admire for his patience, you might be dreaming of that aspect of yourself that you wish you embodied or that you need in a particular situation. Or if you dream of a child you might be dreaming of that part of you that is childlike. If you feel the dream is symbolic, then try to look at the people in it from your inner life.
