I tend to side more with Nopoetic, I think the song is about confusion and disconnection from romance. The fact that he's the only one who "finds it strange when they call it a lovers moon" denotes that he is separated from the notion of love ... and perhaps confused by it. The "question mark" also implies confusion. Love doesn't come as easily and simply to him as it does to the people around him. So, in this sense, people "colliding" could just mean people falling in love, and he looks at them with awe and wonder because he doesn't understand how they do it so effortlessly.
