Dream of

Every so often, there is a guy who enters my dreams. I loved him for a very long time even though we never dated. I haven't any contact with him in years. I haven't even seen him in passing for over 6 months. Sometimes, he's just in my dreams in a minor way and we don't usually talk in my dreams. Last night, I dreamt that I was going to a party with a girl and I ran into him. He looked older and had a beard, but he came up to me and talked to me and whisked me away from the girl I was with and kept me by his side for the rest of the night. What does this mean?
