The reason Richie couldn't sleep wasn't because he wasn't tired, or because the floor was too hard. It wasn't because he had too much things on his mind, or because he was too excited about something either. Nah, none of these were right. The real reason was that Richie was afraid. He was scared of the moment he would close his eyes, of the moment the darkness would envelop him. Well, that wasn't quite true: he would've preferred the obscurity over what waited for him as soon as his eyelids would shut down. He would've preferred being engulfed by the black nothingness of sleep rather than having those dreams. (Or: Richie have a nightmare and the Losers are here to comfort him)
