I Am Really Not a Dragon!

I was addicted to wilderness adventure and died unexpectedly. The good news is, I traveled through time. The bad news is, I went through an egg. When I emerged from my shell and faced the wild mountains and venomous snakes and beasts, my young body shivered. As a result, I waved my furry paws and realized that these were chickens and dogs. I was the existence at the top of the food chain, a mythical creature that transcended civilization. After I transformed and returned to human society, I tried my best to hide my minions for fear of being out of tune with this world. Only later did I realize that the other side of the world was full of monsters! The book is also called: "What Am I?" "Monster's Fantasy Journey"
