Yeah, I do this, as well. I wanted, SO BADLY, to attend Hogwarts, and be friends with Ginnie, Tonks, and the rest. Before this, I remember wanting to be friends with The Sacketts (Louis L'Amour). There's an awful lot of years between the two, and I'm sure there were other times, but these two come-to-mind, right now.
I don't think there's anything wrong with it----I'm thinking it just has to do with our being creative, maybe, or because we think in pictures, or something like that.
