СОННОЕ ЦАРСТВО coll NP sing only fixed WO

(in some place there is) peace and silence because everyone is fast asleep

by extension inactivity in the workplace: the land of Nod dreamland (extended usage) у нас в отделе - сонное царство = everyone in our department is just whiling away the time our department is totally dead.

У вас тут, я вижу, сонное царство: и отец спит, и дети. I see everyone here is in the land of Nod: Dad's asleep and the kids are, too.

В нашем отделе работы по горло - еле справляемся, а у них в отделе - сонное царство: клиентов нет, никто ничего не делает. In our department we're up to our necks in work and can hardly manage, whereas their department is totally dead: they have no clients and nobody does anything.
