Dream About Crush Singing High Notes

I was at school and the guy I like in real life my crush was there and he keep doing things to try and get my attention than kids outside the class were skipping and the teacher was dropping them to the floor for skipping class and than I saw my sister running from them cause she was skipping and than she told me why and it was cause her teacher was a pervert and than I went back inside class and they were singing doing a hole thing and the guy I was just talking about my crush was the main singer in it singing high notes I do not remember what he was saying
