In Islamic dream interpretation, seeing an ex-lover in a dream can carry various meanings depending on the context of the dream and the dreamer’s personal circumstances. Here are some common interpretations based on traditional Islamic perspectives:

1. Unresolved Emotions: Dreaming of an ex-lover may indicate that you have unresolved emotions or thoughts about that person. This could be a sign that you need to address these feelings and seek closure, either through reflection or through actions in your waking life.
2. Nafs (Desires): The appearance of an ex-lover in a dream can sometimes reflect the nafs, or lower self, which is associated with desires and attachments. This dream might be a reminder to assess and control your desires, focusing on spiritual growth and self-discipline.
3. Tests and Trials: Seeing an ex-lover in a dream might symbolize a test or trial. It could be a way for you to confront past experiences and learn from them, ensuring that you do not repeat the same mistakes in your current or future relationships.
4. Memories and Reflections: The dream could be a reflection of past memories. It might not have any significant meaning beyond the resurfacing of past experiences, especially if something in your waking life recently reminded you of your ex.
5. Longing or Regret: If the dream evokes strong emotions such as longing or regret, it might indicate that you are still emotionally affected by the past relationship. This could be a sign to seek healing and move forward, trusting in Allah’s plan for your future.
6. Spiritual Message: In some cases, dreams in Islam are considered to carry messages or warnings. Reflect on the details of the dream and your current life circumstances to discern if there might be a deeper message or lesson for you.
7. Personal Reflection: Consider the actions and emotions within the dream. If the interaction with the ex-lover was positive, it might suggest that you have learned and grown from the past relationship. If it was negative, it might indicate unresolved issues that need to be addressed.

Islamic dream interpretation often involves seeking guidance through prayer and reflection. It is recommended to make dua (supplication) and ask Allah for clarity and guidance in understanding the dream’s meaning. Consulting a knowledgeable person, such as an Islamic scholar, can also provide more personalized and insightful interpretations.

Additionally, the Prophet Muhammad (peace be upon him) advised sharing good dreams and seeking refuge from bad dreams. If the dream leaves you feeling unsettled, it is advisable to recite specific prayers, such as Ayat al-Kursi or the last verses of Surah Al-Baqarah, and seek Allah’s protection and peace.
