Weird dream about my guy friend?

ok, well last night I had the weirdest dream. It was about my guy friend. Before I went to bed I was taking to him online, giving him advice on what to say to this girl that he likes. Well, my dream was really weird. in it I was talking to him online, trying to figure out the girl's name, and he said it was me. Basically there was this whole romantic scene, and besides the fact that this could never happen, it was very realistic, and not surreal at all. I don't like this guy AT ALL, actually I kinda like his brother(a little, not alot). Plus he is older than me, and his brother is my age, so it makes more sense for me to like his brother. But now i am starting to think of him differently. Is this just because of my weird dream? Also, can someone explain this dream to me? serious answers only, please!
