Dream Of School Trip Hiding From Ladies Transforming Into Children

I was on a school trip and I was always with a friend of mine. we had a backpack from a suitcase and together we had a case with some formal clothes inside. we traveled by bus. some people from our school were playing music and singing inside the bus. they had brought two drums, a guitar and a microphone for the singer. in the back of the bus were two ladies chasing us. we were constantly trying to hide from them. At one stop, we went to the back of the bus when the ladies weren't looking and hid under two seats. when the ladies came down, they seemed to be looking for us and transformed into two children.I recognized one, she was a fellow camper from the last summer at camp, I never liked her. They took the next bus, which passed right next to ours and they were looking inside our bus to see if we were still inside, and I think they saw me. then my friend told me that if they get back on that bus again, we all have to go out together, our whole school. and we went forward to tell the professor who accompanied us what was going on. the professor was not one of those we had in high school, he was a professor who taught the next section, in the elementary school I went to. when we got to the front, we were trying to fit the case of formal clothes into some kind of suitcase, so that we could run if necessary. at that time the professor said that we were getting off, but while we were getting our things to get off, the driver closed the bus door, and left, the professor tried to explain to him that we had to get off and asked him if he could stop there for one minute. The bus driver refused and continued. Then me and my friend started to have suspicions that the driver was in the bay with the ladies who were looking for us. The bus stopped, only one door opened, the ladies got in and my friend and I looked at each other scared, then I woke up.
