Wierd dream or a door of fear?

This is my dream and I'm just wondering what it means. So here it is:

The dream was me at somewhere, and then I was talking to one teacher, I forgot who, and then my crush was there...( I'm not telling the guy's name to y'all so I'll just say HIM instead)
He wasn't talking like usual, and he looked bummed out
So I was feeling really sick of my problems, that I just broke outside. Where he was sitting, his back facing me
He didn't turn around, and I was crying hard until I blacked out.
Anyway! I woke up a second later finding myself inside. Then here comes the scary part
I saw HIM shouting or yelling at that forgotten teacher.
He looked alarmed and hurt
I looked around me, then back at HIM, and saw he was hurting the teacher.
I straight up ran fast behind him and pulled him. He wouldn't budge
I looked at his face again, and he still looked hurt. I was yelling at him, "stop, please! I said STOP! "
He stopped, and looked at me, then the teacher.
It was scaring me, I think he saw that in my eyes. He looked hurt, his face was making me feel, I don't know. I heard police sirens in the distance, and looked that way
He looked at me one more time, and gave me a worried but protective look( sorta)
When I looked back to him, he was gone
I had to leave I told myself, then blacked out
I woke up( for reals) and took a deep breath. I sat up straight, and my eyes were darting around the room, and I felt tears in my eyes.
