Dreams involving ex-partners can often stir up complex feelings and unresolved emotions. Your dream seems to reflect a mixture of nostalgia and temptation regarding your past relationship.

Seeing your ex outside a grocery store may symbolize a chance encounter or unresolved issues from that relationship that you still think about. The tickling and flirtatious behavior suggests a longing for the excitement and affection that may have been present in your past. It's important to note that enjoying this attention in your dream doesn’t necessarily mean you want to rekindle the relationship; it might just indicate a desire for emotional connection or validation.

The act of shopping together, particularly buying donuts, could symbolize indulgence and pleasure. Donuts are often associated with comfort and enjoyment, which might reflect your desire for fun and carefree moments. However, your refusal to return the shopping cart may signify a resistance to fully engage in that part of your past or a reluctance to let go of your current life.

Overall, this dream could be encouraging you to explore your feelings about your past relationship while also recognizing the importance of your current commitments. It may be beneficial to reflect on what aspects of your ex's attention you miss and how that relates to your current relationship. Consider what you truly want in terms of connection and affection moving forward.
