I've had this strange dream in which I was in a class but not exactly in my own school. It was actually a mix of two classes I have been in before, with a ton of people I have known in the past.

One of the people who've stuck out to me was a guy who I like but havent seen in a while. He didnt look at me. He was paying attention to the class, the same serious expression i've seen him look before in a class. My ex boyfriend was also in the back of the room. And my best friend was there

The weirdest thing ever, was the teacher was an old mean teacher i've had from elementary school and when I was up front in the class, I urinated myself on purpose. Then I woke up from the dream.

Today my best friend came over my house and I was telling him about the dream...and he told me he had the same dream as me, in the same classroom, with the same people, with the same teacher urinating..and people sitting in the same exact seats. In his dream, he also had seen everybody wearing the exact clothes that I saw them wearing in my dream.
What do you think this means?
