Answer:
The meeting in the place with no darkness between Winston and O'Brien was perceived as a place that Winston feels instantly that he recognizes this place.
Explanation:
The expression "the place with no darkness" is introduced actually into this excellent novel in Chapter 2 at the introduction, when Winston dreams of O'Brien, and is repeated at various other phases throughout the novel.
The impression of this phrase and dream is an indication that the future Winston Smith sees and how vital the part O'Brien will play in that future, even though it is in different way radically, from what Winston thought
Winston finally gets to the Ministry of Love, and meets O'Brien there in a place with no darkness, he immediately feels that he knows this place before now.
This is one of many ways that Orwell foreshadows the future in this novel and points towards its rather unrelenting close and grim.
