Dreams deal in symbols and metaphors. For whatever reason, your subconscious mind has picked up the image of the "guy you don't know" and is using that image to represent something or someone in your dreams. It has nothing to do with the actual person. Other details in the dreams, such as the location they occur or the behavior of characters in the dream might provide clues to their meaning.
If you dream about a boyfriend/girlfriend it doesn't mean that they love you. Probably it means that you love him/her instead or you're just analyzing them as a person (flaws and everything) inside the dream and seeing if they are fit for you.
You guys are not meant to be
it could mean that you want more with this friend
It means you have issues.
The dream indicates that the dreamer remains emotionally attached to the ex-girlfriend and has not yet completely accepted the fact of their break-up. The dream does not provide any information about the ex-girlfriend's thoughts or feelings, or anything about her new relationships.
This might be a wish-fulfillment dream, assuming the dreamer still has lingering attachments to the ex boyfriend. More importantly, this dream is all about the dreamer's emotions and reveals nothing about the ex boyfriend's feelings. The dream does not predict anything in the future.
everything about you is perfect like a dream girlfriend he always wanted.
That you wanna make out with him :)
I don't dream about your girlfriend
This dream suggests that the dreamer feels some jealousy or perhaps fears that she cannot compete with the former girlfriend. The dream illustrates the dreamer's own feeling; it provides not reliable information about the boyfriend's or the ex's thoughts, emotions or behavior.
This song means when your a teenager your boyfriend/girlfriend will not worry about your looks but what's on the inside!
This means that your girlfriend feels that she needs to change something about you but this can also mean that you believe that you have imperfections on your body and that you are uncomfortable about yourself and think that she is uncomfortable about being around you and that type of material. More specifically, the dream is about the girlfriend's own feelings. The dream suggests that the dreamer needs to improve the boyfriend by removing imperfections. Similarly, the "boyfriend" in the dream also is a metaphor, representing some part of the dreamer's own character that needs improvement, or some area of her life that needs cleaning up.
