A dream about a girl.............?

In 3rd grade i had a crush on a girl. I knew that she also like me. She moved away and that was the last time I saw her. At random times i have dreams abut her. Last night i dreamed seeing her walking outside my bedroom window, I ran outside to talk to her but she was gone i searched for her but never found her. Then i woke up. Now im in 10th grade but I never forgotten her nor seen her since 3rd grade when she left. What do you guys think the dreams mean ? Will i see her?
