Shouldn't This Be a Dream?

When Lin Ling woke up, she found herself lying on the black dragon's dinner plate. Facing the protruding big mouth, Lin Ling had an idea. She pretended to be a toothpick in the hope of being ignored by the dragon, but she was not so lucky. Lin Ling was confused when she woke up again. Isn't this right? Shouldn't I be in the classroom? Where did this come from? Lin Ling turned to look at the beast-eared girl next to him who was locked in a cage like him and asked? Could it be that you just traveled through time while sleeping in class? When were there so many places for time travel?
