What does this strange dream mean?

I dreamed of a guy I never had feelings for. I see him during science class and he already has a girlfriend. Well, the dream was:
“He called me on the phone and we talked a little then he said he liked me. I was surprised for a while then I said I liked him back. The next day, I saw him at my place sitting on the ground with his girlfriend watching TV and when he saw me, he gave me a wink”.
