I don't think Adam is still actively running after the man, though. I think this is after the man is already gone, and Adam's still stuck with the memory. This song is all about the aftermath of losing someone you love, and how it always feels like something's wrong. After a huge shock, people often feel like they're disconnected from the world and that there's no real attachment between them and the people around them. Thus, it feels like he's "asleep".
