I'm not sure I understand what you are saying should happen instead of that. A 'you are too confused to open the door!' message? What about going up/down stairs? Should the pc be too confused to do that too? What about saccing? Picking up/dropping items (if you don't have the coordination to get your hand around a doorknob and pull, how can you get it around something on the ground to do the same)? I mean, there's a whole list of actions that you could argue confusion should affect.
Not downvoting, I just think this is kind of overkill.
