Dream of

I dreamt of my ex, she's so clingy. And it feels weird because in my dream I know that we're no longer together. The setting is jn the past, and I told her that i'm from the present. I was about to tell her that she's going to break up with me for another girl but then she doesn't believe in me until the light from the present appears and i need to back. I left her jn the past as i was crying.
