The lecturer supposed to grade my presentation fell asleep while I held it. Should I complain? TLDR:
I am attenting a seminar where the grade is based entirely on a talk I hold. The responsible lecturer fell asleep during the talk multiple times, and I am worried about my grade, feel insulted and am unsure how to communicate these issues.



For a seminar, I was required to hold a 45 minute-talk about current department research in front of the course. The corresponding researcher attends this talk as well.

Together with the lecturer (the instructor for this seminar), they grade my talk, which amounts for the entire seminar grade. The researcher can make comments about how accurate the presentation was, but the ultimate choice of grading is with the lecturer.

During my talk (actually not too far in), the lecturer fell asleep for a bit for the first time, for only a brief period. Now this happened on multiple occasions during my presentation, and it has happened during someone elses' past talk on an earlier date as well.

I find this highly insulting, since I have spent a lot of time reading up on the topic and practicing to hold the talk. 

Since the lecturer did not hear or see my entire talk, I am worried that grading may be affected in addition.

The lecturer is notoriously busy (which I assume to be quite common) and stressed, but both issues should not affect me or my grade in my opinion.
Also, he may have had stress-related health problems in the past, which could be a reason for him to pass on caffeine consumption. I see that this may be a reason for his tiredness, but again I cannot possibly account for it and I should not be graded differently because of it.



I want to communicate the following two issues, how can I approach this situation?


I feel insulted by the lecturer falling asleep through my graded talk
I am worried about him falling asleep could influence my grade




On a side note, I really like the lecturer otherwise, but I am afraid that making a comment like "please reconsider your sleep schedule" whould be considered highly inappropriate (and rightly so). Recommendations on this matter will be appreciated as well.



Update: Grades are out as of today, and I am not satisfied with the grade. I don't have any pointers on what I could have done better or how to improve future talks. I will probably not pursue this any further. 

I don't know if I wrote this in a comment already, but in another seminar I attended, a similar thing occured for another student.
The first thing to note here is that sleeping in such situations is often not a voluntary action, but a physiologically unavoidable response to the situation the body is in - many people die every year after falling asleep at the wheel of a car. I don't think you'd describe the results of that on other people in the car as "rude". In general, if you are in this state of involuntary somnulence, then no amount of caffeine will change anything. 

You do not know the circumstances in which this lecturer is in: casual lecturers or adjuncts may be working several other jobs, or may have insufficient income to afford rent and therefore a proper place to sleep. Permanent folks may have so much work that they literally don't have time to sleep and complete everything they are required to do. Or they might have a young child or as you say, mental health problems. My point is these things may not be voluntary choices for the person concerned. 

If i had a dollar for every student that fell asleep in a lecture that I had spent days preparing... 

But....

None of this is your problem. You deserve not just to get the correct mark for your work, but also the feedback that will help you improve - after all, you are there to learn, not to get grades. As others have said, wait and see what the feedback is (and really you want proper feedback, not just a grade). If it's fine, then I'd wait and see, but even if it is - if this becomes a pattern then it might be in everyone's interest, including the faculty member's (depending on how understanding the Chair is), for people to know what is going on.
