Alice's Adventures in Wonderland and Through the Looking-Glass
"I can't believe that!" said Alice.
"Can't you?" the Queen said in a pitying tone. "Try again: draw a long breath, and shut your eyes."
Alice laughed. "There's no use trying," she said: "one can't believe impossible things."
"I daresay you haven't had much practice," said the Queen. "When I was your age, I always did it for half-an-hour a day. Why, sometimes I've believed as many as six impossible things before breakfast." (Looking-Glass 5.53-56)
"I only wish I had such eyes," the King remarked in a fretful tone. "To be able to see Nobody! And at that distance too! Why, it's as much as I can do to see real people, by this light!" (Looking-Glass 7.8)
"So I wasn't dreaming, after all," she said to herself, "unless – unless we're all part of the same dream. Only I do hope it's my dream, and not the Red King's! I don't like belonging to another person's dream," she went on in a rather complaining tone: "I've a great mind to go and wake him, and see what happens!" (Looking-Glass 8.1)
