What does this dream about an old friend mean?

Ok so when i was ten i met a boy and we were just friends after that summer we lost touch and he graduated from high school in 2012 i miss him and i had a little crush on him, but now I tried to add him to Facebook and his gf deleted me . I had a dream about him i dreamed i logged on Facebook and he had posted a new video and i watched it. I was wondering what did this dream mean?
