Back to School

I dreamt I was back in school and either the principal or a teacher there was very very mean, calling me a liar and wanting nothing to do with me like I was too low class to be there. At one point she had this little dog that she was being mean to, I picked it up to take it home, we were outside, near some water, and she punched the little dog in my arms, I then punched her and knocked her into a pond or fountain. I woke up then.
