Crush from high school

hi im a 24 (f) who've been having very intense dream about her high school crush, mind you I had that crush in 2015 when I was 15 and now we are in 2025, I graduated in 2017 and I haven't seen the guy since then, I can't find him on social media which is kind of annoying but I respect it, it's just for the past couple of months, I've been having vivid dream of this guy, in many different scenario and weirdly enough he always reject me in my dreams, also since we never was really friends in high school, I don't even know him nor his personality like I said it was a teenage crush nothing too crazy, and since i've moved on, I had a boyfriend and met many guys after him but just weird that im stuck to a person I haven't seen in the past 8 years, and im stuck with the physical version of him of 2015, i don't know what the guy look like right now, I could had passed him by and never knew it was him... I really feel so stupid, I know it's limerance but idk how to get rid of it, for a soul that need solution...
