Wonderland- Red King's Dream

Here she checked herself in some alarm, at
hearing something that sounded to her like the puffing of a large
steam-engine in the wood near them, though she feared it was more
likely to be a wild beast. “Are there any lions or tigers about here?”
she asked timidly.

“It’s only the Red King snoring,” said Tweedledee.

“Come and look at him!” the brothers cried, and they each took one of
Alice’s hands, and led her up to where the King was sleeping.

“Isn’t he a _lovely_ sight?” said Tweedledum.

Alice couldn’t say honestly that he was. He had a tall red night-cap
on, with a tassel, and he was lying crumpled up into a sort of untidy
heap, and snoring loud—“fit to snore his head off!” as Tweedledum
remarked.

“I’m afraid he’ll catch cold with lying on the damp grass,” said Alice,
who was a very thoughtful little girl.

“He’s dreaming now,” said Tweedledee: “and what do you think he’s
dreaming about?”

Alice said “Nobody can guess that.”

“Why, about _you_!” Tweedledee exclaimed, clapping his hands
triumphantly. “And if he left off dreaming about you, where do you
suppose you’d be?”

“Where I am now, of course,” said Alice.

“Not you!” Tweedledee retorted contemptuously. “You’d be nowhere. Why,
you’re only a sort of thing in his dream!”

“If that there King was to wake,” added Tweedledum, “you’d go
out—bang!—just like a candle!”

“I shouldn’t!” Alice exclaimed indignantly. “Besides, if _I’m_ only a
sort of thing in his dream, what are _you_, I should like to know?”

“Ditto” said Tweedledum.

“Ditto, ditto” cried Tweedledee.

He shouted this so loud that Alice couldn’t help saying, “Hush! You’ll
be waking him, I’m afraid, if you make so much noise.”

“Well, it no use _your_ talking about waking him,” said Tweedledum,
“when you’re only one of the things in his dream. You know very well
you’re not real.”

“I _am_ real!” said Alice and began to cry.

“You won’t make yourself a bit realler by crying,” Tweedledee remarked:
“there’s nothing to cry about.”
