Was it a warning? Or it was only just a dream?

         I was busy preparing for my hockey match which would be held the next day, on the 13th of September. We would be playing a friendly match against students from Somali.  As I had done hanging my number 13 jersey and track bottom, tiredness ruined into my body. I slowly dozed off....
         I was standing in the middle of the school field. With a hockey stick in my hand, I was running beside my teammates as a part of our strategy. My number 13 jersey was soaked wet. Everyone around us was cheering and I could hear my coach busy giving instructions. As we were attacking, out of the blues the opponent got the ball. Without hesitation they counter-attacked. I had to run back as fast as I could as I was playing as a full back that day.
        The player of jersey number 8 passed a long ball to his teammate who was running behind me. I was very confident to have gotten the ball. However, lady luck was not on my side. My judgement was wrong and the fast ball hit my knee. I could feel the sharp shrink of pain. I gave out a loud yell before collapsing to the ground. Everybody was in a shock! The medical crew came to me. After checking my knee, the physiotherapist said that I could not play hockey anymore as I would have problem walking or running. I cried my heart out as hockey was part of my life.
        "Alvin, are you okay?" I could hear my mother asking politely beside me. Slowly I opened my eyes. I could still feel the pain on my knee although nothing was there. My pyjamas was in a mixture of my sweat and tears. I looked at my number 13 jersey and the calender. It was 13th of September! I remembered my grandmother once said that 13 is a number of taboo and asked me to avoid it.
         I did not turn up for the match that day....
