Vision: If you are lonely and dream about a friend, it means you want to have a better social life. Meeting a friend: a warning to think before you act! Seeing a deceased friend: surprising news. Helping a friend: you too will soon get help. Starting a new friendship means you have really good, true friends.
Depth Psychology: Meeting a person you know: the feelings you have for the person in the dream are the same as those you have for a friend in real life.
