Simone, your dream of an ex washing and folding your underwear is laden with layers of subconscious symbolism. The act of washing signifies a cleansing or purification process. Given that it is your ex performing this task, it may represent unresolved feelings or a desire to cleanse past issues related to your previous relationship. The involvement of your underwear, which is intimate apparel, suggests that these unresolved issues are deeply personal and may touch upon your self-esteem or vulnerability.
The folding of the underwear by your ex could imply a need for order or control over past emotional disarray. Folding is an act of organizing and tidying, indicating a possible desire to compartmentalize past experiences to make sense of them. This action by your ex might symbolize a part of you that is trying to reconcile with the past and bring closure in a structured manner. It could also reflect how you are currently attempting to manage aspects of your personal life, especially those that pertain to your intimate self.
Considering your frequent stress and anxiety, this dream might be a manifestation of your mind's effort to process these emotions. The presence of an ex could also signify a part of your life that you are not fully done with, emotionally or psychologically. This dream might be urging you to address these feelings so that you can move forward more freely and with less emotional baggage.
Additionally, your history of relationship difficulties and substance abuse might be reflected in your dream.
