Dream Of Encountering Ex Friends At The Beach And Feeling A Range Of Emotions

I was with my ex friends from a camp. I've been with Youra, Nika,Kostya and other members of my last group. We were on the beach. I laughed with Nika, because we're trying to find a beach changing room. When we found it out, we met Youra. I tried not to cry out, because of how much I missed him. We hugged each other tightly and laughed for a while. After we greeted each other, we went to other members, but before we went away, we also met Kostya with his mom and...brother? Idk if he has a brother or not,but I saw a teenager near him, eho was like him. And then we went to other members of our group and we were enjoying our time, until Nika approached me and tapped my shoulder softly. I turned around to her, and I saw sadness in her eyes, before she said "bye". And then I woke up.
