I think that the desire that was meant to be met within the nightmare was the chef catering for the foreign diplomatic meeting.
He was nervous about not doing it and him scheduling his surgery on the same day was probably a way to try and force himself to need to leave it to his students. If he didn't have an urgent top-priority event like that he likely would have tried to take over himself out of fear they couldn't accurately make the sauce.
He wasn't catering IRL but in the dream world it's shown that he directly cooks for the event so in that extent the nightmare was close to fulfilling that, if that's intended to be his bad wish.
