When he slept he dreamt of living a life as a professor of biomechanical engineering at Boston University. When he woke he was a component in the ISS, his three inch metal body significant in holding the hull together. He would often forget his dreams quickly after waking but he sometimes wondered if his dreams were real somehow. Either he was observing the life of JJ Collins or he was in fact JJ Collins who dreamt of being a bolt integral to keeping the International Space Station together that was unable to tell reality from dreams. A bit like The Matrix but not as action packed.
