Can you tell me what this dream means? btw I'm in summer vacation right no and I broke up with my ex?

Last night I dreamed that I was in school again! It was the last days....but first I was in my house with chachi (cousin) and other girls I didn't know who they were but in my dream I did....then there wpas an elevator and went in it when I reached the top floor I saw cristy (bff) and Alan (ex) Alan grabbed Cristy and said let's go but she resisited then I went to her hug and say hi but she resisited and told me I heard you broke up and I can't believe you didn't tell me. I told her I was but I hadn't seen her during the summer and I saw her with long hair! (her hair is short) So then I started to walk with her and Alan left and has we walked around the corner I saw reny and Jordan kissing! (a girl and a guy who should not be kissing each other!) Cristy and I were surprised! Then I suddenly ended up in some fake desert I stared to walk forward then I was in my dad car and he was driving me to school when I got there the stairs felt like forever! Like my legs were heavy like if they weighted one hundred pounded each. I was there with only a kid he was struggling too (in the stairs). then I was in home room for like two seconds then I went to math. I was with Cristy and we had to write down stuff cuz we had a sub and he told me looks like your single again and I got sad and wanted to cry but I didn't then �we went to lunch and like in most of my dreams getting lunch I always got the number wrong Idk why that happens in most of my dreams and cristy was saying if I get it wrong that's because i was calling the police and she sat down waiting for me then suddenly I was going to home room again I was there longer than the other time and I realized home room got smaller and Alan wasn't there but Abraham (little cousin) was and Harold (uncle) was watching him then Cecilia (bff) was with gricenia(friend)talking and there was no seat for me so yarimar ( girl in school) started telling me about how the room got smaller and I said or maybe we got bigger! Then I heard Nicolas (kid in school) talking some other kid saying it was Tuesday and tommorow was the last day of school then all of a sudden (this was in cartoon) and tinker bell was flying to her house and it was really cold and her wings got frozen and she couldnt fly and she was stuck in the ground.....then I woke up werid dream huh?
