Dream About Dancing With High School Friend

I’m not sure where we were but I know the dream started when I could hear the music where I fell asleep. The song “Just Got Started Lovin’ You” by James Otto. Suddenly I see myself and I look like I did at 19. I was a healthy weight but the same age I am now, wearing the clothes I use to wear. I was also with a friend I met in high school but lost contact with right after high school until recently and we were dancing as though we were out at a bar or club-somewhere fun. This same friend has also shown interest in him and his wife bringing me into a polyamorous scenario recently as well. I seemed genuinely happy for a change too. The song ended and I woke up.
