Dream About Embarrassing Classroom Experience

I was in a classroom that was familiar in context but not visually. I have never been in this classroom in real life but it did look familiar, The teacher was also familiar but not familiar, she was familiar because she was supposed to be my real life history teacher from highschool but my dream didn't have any indications this was history class, my body just automatically knew it was in and outside of them dream, but in this dream she looked like or actually was Madison Beer. I walked in a little late from breakfast downstairs in the cafeteria and was going to my normal spot next to my best friend but half the table was missing and my chair was gone so I sat in my other friend's who was absent chair. I was doing work and was a little behind everyone else copying what was being shown on the screen into my notebook, the teacher who was sitting at my table with me and my friend who was originally absent was making fun of the fact I wrote the wrong date on all of my previous pages in my notebook but it wasn't playful teasing, it was like she wanted to embarrass me in front of the whole class. She pointed out my mistake and started laughing and pointing it out to other kids in the class so they could laugh at me too but while dreaming I didn't notice this so I was also laughing at my mistake. The last thing I remember was a group of 3 boys walking in, one walked over to my table and was talking to the teacher, he then started to go through my work and asked if there was anything he could do, I said no to his two suggestions since I was already done working on one of them and was currently working on the last one. The boy noticed my first page wasn't completely finished and was missing two sentences so he offered to wrote those two last sentences, I said yes since I couldn't hear what the two last ones where. The teacher got upset and asked me "You're really gonna let him do your work?" I was explaining to her that I already did everything, I just couldn't hear what was said so I agreed to let him help and when he was finished writing I would erase it and then rewrite it so it'll be like I did it, I suggested that thinking it would be better and maybe calm her down, we went back and forth and the boy got uncomfortable and said he was gonna take off, the teacher said something indicating she wanted him to stay but he said politely said he was fine and then left. The teacher looked at me, said something and then gave me detention, she was upset that I made the student leave even though I didn't do anything, I was hurt and felt really sad that this teacher did not like me and was tearing up over this student I have never met before so Inwad apologizing and trying to understand what I did wrong, I offered to do whatever she wanted me to do to make it up to her and she said not to talk to her for the rest of the day so I said "ok" before I stopped talking to her I asked her if I can take the last piece of work I didn't finish home since class was over and she snatched it away from me indicating she was gonna grade it regardless of it not being done, I then asked about the other work and she shook her head no while looking back and walking away, I shook my head in understatement and stopped talking to her like she requested, I asked my friend where to put our notebooks and class stuff and he was showing me where every item goes and then I woke up.
