O'Brien and the Horrors of Room 101

1. O'Brien is known as a member of the thought police. When he was in Room 101 torturing Winston, he couldn't read Winston's mind, in fact O'Brien has a connection with Winston. Back in Part 3 Chapter 2, O'Brien mentioned that he was in the same position that Winston was getting beaten by guards because of the thought crime he committed years ago. Plus he has been in most of the tortures in Room 101, so that tells me that he can tell that the tortured person's feelings and what might they say next in response to his questions. Concerning the part where O'Brien was spying at Winston seven years ago, I do believed that O'Brien permeate Winston's dream during that time. Even though it is impossible to permeate people's dream, Winston was probably sleep talking and O'Brien brainwashed his dream by talking to him using the power of the telescreen.

2. During Winston's torture in Room 101, O'Brien had mentioned to him that the Party was going to kill him sometime in the near future. But before he dies, O' Brien told him that he will continue with the torture until he accepts, and love the party and Big Brother. Even thought the people getting tortured in room 101 will not return to society, the party will continue with the torture and "rehabilitation" to make them love and accept the party and Big Brother. It is the only was the Party can brainwash people that hates Big Brother and the party into loving it without any doubts of turning back to their old thoughts. It is the Party's way to forgive thought criminals for their hatred of the party and Big Brother by giving them the favor of changing the though criminal's beliefs into loving Big Brother and the party with their tortures inside room 101.

3. Room 101 is the room where torture takes place from the party to "rehabilitate" people into loving Big Brother and the party.
