A weird adaptation of "The Sixth Sense"

There is a man at the gym who is rather old and rather rotund. I never see him on the gym floor, working out, though. Anytime I see this man, he is invariably wandering around the locker room completely stark naked, with a towel draped over his shoulder. Just walking around. Or there's also this little lounge area inside the locker room with a television and some nice furniture. Sometimes I'll see him, again entirely unclothed, sitting on his towel, which he has laid on top of the nice leather chair. Just, you know, hangin' out. I am beginning to think this man is imaginary, that he does not actually exist on our physical plane. He may be a man who died on the grounds somewhere, and his disconnected spirit looms around the locker room, carrying on his life as he did before he died. Does he know he's dead? And for that matter, why doesn't he put on some damn pants, already?
