Not really spoilery, but in consideration of GD's request:

Spoiler:

If it was the little helper book, understanding he only got it a couple days earlier, he sure did pick up on it fast. A dream would be a dramatic device that they haven't used yet, and I suppose they could introduce it, but everything they've shown about the survivors has been real to the character thus far in the show. I am more inclined to think it is a flashback and that he has known English this whole time.
