What does this dream mean?

I keep having a certain dream and I need a translation. The jist is that in my dream, my ex and I still have feelings for each other and one way or another we are trying to avoid each other, trying to get together or only one of us is trying to get us back together and we are always at school. Also, everytime I want to walk or run I can’t, almost like running in water. I’ve had this dream for about two years now and I don’t understand it.
