What Does Dreaming of a Heart Mean?
Traditional Interpretation
According to Ibn Sirin, the heart in a dream may point to one's faith, character, courage, intelligence, and generosity; seeing the heart white and radiant signifies good intentions and purity of heart, while seeing it soft signifies compassion. By contrast, a heart that appears hard, black, or diseased may point to straying from the truth, hard-heartedness, or hypocrisy.
Psychological View
From a modern psychological perspective, the heart represents the dreamer's emotional center, the poles of love and hate, and repressed feelings; seeing the heart may indicate a need to listen more closely to one's inner voice and true emotions. In the Jungian approach, the heart can be a symbol of the search for integration between reason and feeling (the Self) and of the need to reconcile with one's genuine emotions.
