Dream About School Singing Mysterious Songs

I had a dream where it was a few days after the last day of school in 9th, I hadn’t gone on my vacation yet, I was in a big room with chairs, everyone at the school was sitting on the chairs, singing songs that were made up from my dream, and they sounded rather dark. It was honestly quite fun to sing the songs, though. This might’ve been the same dream, or a different one, but I was buying really nice clothes with friends that were from my 8th grade class and I couldn’t tell if I was in Texas or Oregon, but then at one point my friends and I sang a song that was more lighthearted with three or four part harmonies, and someone even recorded it. There was another dream where for some reason, school continued on even after the last day of school for some reason after I went on vacation, and there were over four assignments I missed where I had low grades on all of them. that dream was most likely a nightmare, but it didn’t immediately wake me up.
