It is very common in IF to use the second person for the player, rather than the first/third, as well as having the possibility to choose one's name (especially when the player doesn't know their name). Personally, it didn't feel like it added to the confusion and I am not sure where the game needed more disorientation. The story itself was pretty disorientating to begin with :)
I think the NSEW would then fit best with your need (or have a map menu that uncovers parts as the player passes through rooms?)
