I just remembered this book series that I read as a teen. I can’t remember the name of them and it’s killing me! I know this a long shot but here it goes:
It’s about a girl going to college (or it could also have been some sort of private high school that has dorms). Weird events start happening while she is there. It’s a series with maybe 3-4 books. She tries to solve the events with a friend I think?
I don’t get the impression these books were best sellers at the time but I could be wrong. Like I said I know it’s a long shot but I just had to try. Thanks!
