What Does Dreaming of Your Ex-Lover Mean?
Traditional Interpretation
According to traditional interpretation and Ibn Sirin, seeing an ex-lover in a dream may often point to a new relationship, good fortune, and joyful news; since Ibn Sirin says that a gaze signifies the intention hidden in the heart, this dream can also be read as a reflection of a longing quietly carried within, or of an unresolved matter.
Psychological View
In modern psychology (within the frame of Jung's concepts of integration and the shadow), the ex-lover usually represents not the actual person but an emotion experienced in that relationship, a missing piece, or an unresolved issue; it may indicate that the unconscious wants to carry a lesson from the past into the present.
