A picture of a relative or friend falling off the wall for no reason: illness or even the death of that person. Seeing pictures of your deceased parents or friends: freedom from an unpleasant situation soon.
The picture of a child, a woman, or friend: you will soon receive some new information.
Depth Psychology: Seeing a picture of people that are part of your immediate world often is a challenge to try to get to know them better. Sometimes we see pictures of people in a dream before we have even met them. Seeing ones own picture/photo in a dream is a symbol of what we know and what we think about ourselves.
