It is very disconcerting. It pushes my sense of disassociation out a bit - which is usually not a problem, I like that "this isn't really real" sense, but it has been happening a LOT lately.
Speaking of noticing things... There is this guy I see on my way to work. At first, I thought he was a college student. He has that casual look. Then, I realized he walks away from BCC every morning. In any case, there is something about this guy that just makes me go *rowr!* I want to rip his clothes off and lick him from head to toe! Who cares that he's probably at least ten years my junior. Want. Now! I don't see him every morning but the mornings I do... *leer*
