Dream About Dancing In A White Room

I came to this large white room with a few square concrete pillars of a building, after walking pass many other rooms. It looked more like they didn't build any room in this area, so it was like a huge room instead. I turned around as I sensed someone behind me. It was a boy in white shirt, tucked in black pants. He had a set of dj with him, and he started to play his music. The music was so good I started dancing, shaking and kicking around although my dances were terrible. I even wanted to try popping and locking because I remember about this style. So I did try it and embarrassed myself. He tossed the set to me, and started dancing as well. It was so fun, with two people, in a huge echoing white room. It felt lonely. We didn't say a single word, we only danced and the only noises were the music and our jumps. His face barely had any emotion. It felt like he was also lonely, so much that he is used to having no expression. But i knew that he was having the best time, and I did as well. Now I was walking through the corridor of multiple buildings of the school. The sky was undefinable, it seemed dark but it wasn't night nor day, there was no specific weather. I can only see clearly first part of the building, and the corridor is dark when I look straight forward and everything will only reveal if I walk near them. Each building belongs to each nationality and they teach in their own language. Of course I have no idea what they were saying. I was passing through another classroom, and noticed the male teacher was frustrated with a male middle-school student and trying to be strict with him (similar to what happened to my situation). So I knocked on their blackboard three times, but it didn't make a loud sound and barelt no one noticed. I tried again but it was the same. So I turned to a desk, and slapped on it. Now I got everyone's attention. I had no idea what they were speaking, but through their body languages and context, It felt like the teacher was making the student speak then speak over him to overwhelm his student by his higher position. So I used my body language and my own language to signal them to let him talk, they somewhat resisted at first, but the student finally said something. I didn't understand, but it didn't matter, what mattered was that he spoke up. So I made a thumb up then left, hearing the students' laughter and it made my day.
