It was some thoughts occurring to him that he was trying to hide. Now this very passage you mentioned shows the trust and friendship he has for Sancho, by partly admitting to him his doubts, but it is by asking Sancho to play the game, to help him hold to his illusions.
I really think the characters in this books are somewhat acting like kids, mainly Don Quixote and Sancho, but at the same time, all of them to a certain extent. I have remnisciences of when I was a kid creating myself fantasies and there was not this "need" not to really believe it at the moment, and then Sancho reminds me of those who would sometimes get into my games, as games, but still taking it seriously. A kid gets caught in his fantasies a bit like Quixote (although for Quixote, it's a sublimed version, but with the same principle applying).
