It was seven years ago.I am a freshman, at that time I was in elementary school.Remember to be a very hot summer vacation, we still live in old house, my mom and dad sleep in a big bed.Dream, a like ferris wheel in front of my eyes, almost two or three metres high.Above all tray, behind me there was a white hair wearing a white coat like Dr With glasses, he let a group of children on the "wheel", a ferris wheel began to turn, then each tray back out of the metal claw, the children in the stomach to wear in the past, their guts out in the belly, also keep vomiting blood in the mouth, the children all dead, however, before the PAWS in their belly wear to wear to...The doctor laughed, and then pointed to the "wheel" said to me: "you see, this is what I just invented instrument of death."Then I woke up, the whole body is sweat, parents are sleeping dozen freed, I looked at the clock, just 12 points, that night I had insomnia, sleep until dawn for a while.
