Hogwarts: the Forbidden Eldest Daughter of the Dursleys

My mother in this life is a beauty. Although she is so thin that her neck is long, she is still very beautiful. Her name was Petunia Dursley. Her husband, my father, named Vernon, is a stocky man. And this home is at No. 4, Privet Drive. This familiar information was enough to make my little head throb. Because these people and this address do not exist in the reality I know. They should be fictional characters and places. Alas, I just feel an ominous premonition welling up in my heart. I waved away the uneasiness that kept popping up over and over again, but in the end I still fell into despair - maybe it was just as I thought. My parents were right in front of me, and they looked exactly like the ones in "The Dursleys". This perfectly fits the characteristics of the Muggle uncle and aunt who adopted the protagonist (actually not considered "raising") in the "Harry Potter" series that I read when I was a child. It was so realistic that I suspected that they were the real ones. Is it possible that this is really the world of "Harry Potter"? If that were the case, it would be ridiculous to be hit by a truck and reincarnated again...
