Reasons why I'm a bit of a downy

Ever since I have begun Year 11 this year, I have been some what totally exhausted all the time for no apparent reason. Besides waking up an hour earlier than usual, my school day is the same. Some times a bit shorter. I'm not sure if this has any connection with my fore coming story or not, but my dreams have become a bit odd lately.

This particular dream I was rushing into school because I had a few tests that day. I was a little late but not too late for anyone to notice, and was one of the last few to take their place. On my way to my seat I had a gut renching feeling rip through me. I just realised that this was day 2 of my exams and I had apparently been absent from school the previous day. (any absences from assessment taks in my school are immediately marked 0 unless you have a a doctors certificate) As I sat down I kept looking around as if looking at the other students around me would help. That was when the freakishly tall examiner came over the microphone and said 

"This is your second day of your final HSC exams. Today you will be completing the English exam, followed by science. No cheating and before you start remember... be on the test on time"

Following this sentence I could feel myself falling through the floor. As if I was being swallowed up by the ground. 

I quickly awoke from my horrifying dream and started franticly searching for my science book to prepare for the upcoming test that I had to quickly get back to school to do. After about 3 minutes of pure panic infested scurrying around my room, I started calming down.

It was then I realised that:

1. I didn't have a test that day.

2. I don't do any science related subjects.
