What does this crazy dream mean?

Well, you say you never looked at him twice before the dream, yet you're sure that he looked at you more after the dream than he did before. The fact that you could tell that he was looking at you more was probably just your interest in him due to the dream. My guess is that he was looking at you and you could subconsciously tell that he was interested in you. Other than that, it was a weird dream, I don't think you have to be too worried.
