Dream About Late School Exam Heads Exploding Ran Slow Motion

This dream was about

I was late to school, to enter my class i entered another class, where a male was teaching and scold to me for late. Said, i worked at shop which makes it late. There is a lady teacher in my class. It was examination. Few are on the back and front, and middle was like empty. A boy said come sit here but I sat middle alone. There was something written on the board, first i didn't understand then I madam said quick write those or will clear it. I realised it was answering to our exam. I was little hard to understand the answer, but I figured out. Nitu ( a girl, from childhood school) was arguing with Korean boy about killing something. Then boy came near to nitu and held him. Nut's head exploded, they blame the boy, but I insist I held him and didn't do anything. After few minutes heads are started to explode. We all are running to get out of school, but doors are closed. It opened and we are ran. I didn't have sandals, and Why don't know I ran for stole one. And I unable to run like im in slow motion and other boys are running fast. I'm at sandals and trying a few and my legs are like very big like my mother 's. To try more I ran to other room but I saw some familiar face and stoped. There were girls but a girl ( jharana, from village) asked how was your exam. Said , it was okay .
