What does this dream mean?

In my dream I was my friends girlfriend I used to have feelings for him and he did to because he told my friend and she told me. I never said anything to him. In my dream there was a flood. The setting would change really quickly me and him ended up at a college campus that I go a lot to hang out my x was there having a bbq with his family. He looked very jealous . Me and my friend left we were chiming trees and I could get on to the next one I was very afraid and wanted to get down so he told me to jump he catched me. In my dream we went to the same schools but we don't anymore. What does this dream mean?
