Dream About Evacuating Hometown And Identity Crisis

I dreamed that I was back in my hometown and I was a teenager. My hometown was different. It was crowded and chaotic. There had been something that happened to the community, a disaster of some sort. It seemed like everyone had some kind of unfinished business and they were looking for the person they needed to talk to. I was helping my friends find their people but I couldn't find mine. Finally I saw Carl at a table with other people. He was wearing a fedora and smiling. But then I noticed that the other people with him were different versions of him. There were two other guys who looked just like him but with slight differences and when they looked at me, none of them seemed like Carl, even the third one who was Carl. (In real life Carl has been in an accident and nearly died. He made it through but with significant memory loss. He doesn't remember the last ten years when we had rekindled a relationship we had when we were young. This really happened.) In the dream, I decide that I need to talk to him but it's getting more and more chaotic. People are trying to leave the school and evacuate the city. My friends are finding their boyfriends and making up and they're telling me that I have to do the same with Carl. I finally find him in the crowd and he tells me that he's blocked me on his phone and social media and I just need to leave him alone. I ask why and he tells me that it's because I don't like his hat. I tell him I do but he's awful and I have to walk away. I tell my friends that he is not the same person and probably never will be. They're sad for me and they tell me that they have good memories of Carl too. A friend's mother who I've known forever said that her aunt told her that she remembered playing Bridge on Carl's front porch. (This is a similar incident that happened in real life when I sang at a friend's wedding and her mom, the same woman came up to me to tell me that her aunt said my voice made her cry.) Finally, I had to go and we all evacuated. That was the end.
