I have had this dream a couple of times in the past few years and I'm trying to understand what it means.

The dream is always that I'm vacating my dorm room on the last day of college. It has been years since I left college but this is a recurring dream.

The backstory is the guy ,I was in love with ,told me he had met someone new(even though he said he was in love with me) and it broke my heart.But I did not tell him that and acted like it was cool. I went into depression and never kept in touch with him nor acknowledged my sadness over this .I recently had postpartum depression and was forced to analyze my repressed feelings and this one was the main one. I still have the sadness but I'm trying to let it all go.

Do these events hold any relevance to my dream or what could they possibly mean?
