Analysis

I think that the officials are collecting data of their citizens because they are trying to research about something, about the life of a human being. They want to know how humans die and if its possible to revive them again. The officials collect datas of their citizens by attaching devices of them even when they are sleeping. The officials are able the predict the citizens' movements and read their dreams(my book is a science fiction book).

In my opinion, the officials are collecting  datas in order to advance their knowledge of human beings or their citizens. This way they will be able to farther control and protect the movements and thinking of their citizens, even more than they are controlling them right now in the book.
