Praise Father God. 

In class studying Mathematics in a dream. I was weak, unable to write. I saw other students eating food and wanted to have food also in order to be strong.
Later I saw the teacher taking papers for the test of mathematics in order to mark them, I felt to tell the teacher that I needed time to revise and then do the test the next day though I saw when I had written a few calculations but I felt that I had not done enough revision. While I run after the teacher as he took the answer sheets for marking, I saw my Brother following the teacher. The teacher was my best Friend. I wondered why he wasn't hearing from me
