This dream may be reflecting your subconscious thoughts and feelings about past relationships and how they have affected you. The old apartment represents a familiar and comfortable place, but also a reminder of the past. Cleaning up may symbolize your desire to move on and let go of any lingering emotions or memories associated with your ex. However, the fact that you are waiting for your ex to come home suggests that you may still have unresolved feelings or unfinished business with them. The toxic old friend who appears as your ex may represent the negative aspects of your past relationship, such as toxicity and manipulation. This person may have been a negative influence in your life, and their presence in the dream could be a warning to avoid falling back into old patterns. The lack of affection from this person may also symbolize your realization that your current relationship is much healthier and more fulfilling. Overall, this dream may be urging you to let go of toxic relationships and focus on building a positive and loving partnership in your waking life.
