The Girl Who Lived

It was now or never, it was up to us to save the world.
"Ar' yeh ready?" asked Hagrid.
"Yes." I replied.
We hopped onto our carousel horses, his was black, mine a beautiful magical unicorn. The horse and unicorn set off down the track, quickly picking up speed. I felt as if I was flying. We turned corners, went up hills and sped down them, until:
"NOT SO FAST!" shouted the talking shark.
I floated in the air in front of him, with my wand. We fought until I, of course, won and he floated lifeless in the air. Back on our pretty plastic horses, we carried on along the winding track. It was quite pleasant. Then we saw him. The dark wizard who we had to kill so that everyone could live happily again. Me and Hagrid had to kill He Who Must Not Be Named, or the world would die.
We got out our magical wands and sent spell after spell at each other. Hagrid vanished so it was now up to me to save the world. I dodged his spells and he dodged mine. We were both hovering in the air when I sent the ultimate spell in his direction. Lord Voldemort was dead. I HAD SAVED THE WORLD!
Unfortunately, it was all just a dream.
