just figured I'd say this, sleep is a state of unconsciousness, and yes all the civilians needed medical attention because of the genjutsu because they were not awake because the genjutsu was still in effect. and if you look back even naruto had to have someone cancel it for him for him to wake up, if you pay attention he was passed out on the ground, unconscious, just like sakura is now....just because its more of a torturous thing that could knock her out doesn't mean it did, if she's already asleep she's already unconscious, therefore she would still be caught in it.
Its because the Genjutsu was still around them continuously making them unconscious and they had chakra in their system....which only people who are awake can dispel....they weren't constantly in an illusion.
