Dream of mad

So I have been continuously having these dreams where I see my ex best friend passing by or repeatedly looking at me. Sometimes she looks mad and sometimes it looks like she doesn't care about my existence. But what is creepy about this dream is them she features in my dreams recurrently, and we never speak.does this dream mean that she might be thinking about me to. Because I get a dream about her every night and it's going to be a year and a half since we had a friendship breakup
