Every classmate of yours would have to share traits with you, and judging by the positive reaction you had to all of them, these are all good traits. If they're all in the student council, it might be that you're seeking a decision about something and the student council represents a balanced judgement base. The hiding of the ID cards seems important to me, probably to do with discerning something about who you are...perhaps you feel some part of you is misrepresenting the true self at your core?

The UFO represents a deeper-seeded internal message. I see this because it was there through a false awakening (when you wake up, but not really, and the same image is there the message must be strong...otherwise it would have changed wit hthe dream scape). As for what UFOs in your dream indicate, this is osmething I haven't seen before. I went and looked around to find some general concensus, and the two big themes are higher purpose in life, and the true Self. I'm going to go wit hthe second one here, and say that this is an experience like looking into a mirror, and seeing yourself looking into a mirror...the UFO represents your whole psyche...the complete picture of all of your different characters. That you're seeing it indicates that you're not there yet (you won't ever get -there-, but you can always get close). That you can SEE it, however shows that you're resolving some major issues. Perhaps you need to make some final transitions in life? Some major decisions about who you are and where you're going?
