What Does Dreaming of Jealousy Mean?
Traditional Interpretation
In the tradition of Ibn Sirin and al-Nabulsi, jealousy in a dream can mostly point to an envy occupying the heart, a discomfort felt toward the blessings of others; if this feeling is suppressed or overcome in the dream, it is said to signify a goodness that will ease the dreamer's heart and the virtue of mastering one's ego.
Psychological View
From the perspective of modern psychology, jealousy in a dream can indicate that the dreamer is experiencing a lack of trust in a relationship, a feeling of inadequacy, or a fear of loss in waking life; it may be read as a reflection of the subconscious working through feelings of comparison and possession.
