"Why, it's Ali Baba!" Scrooge exclaimed in ecstasy. "It's dear old honest Ali Baba! Yes, yes, I know! One Christmas time, when yonder solitary child was left here all alone, he did come, for the first time, just like that. Poor boy! And Valentine," said Scrooge, "and his wild brother, Orson; there they go!" […]
To hear Scrooge expending all the earnestness of his nature on such subjects, in a most extraordinary voice between laughing and crying; and to see his heightened and excited face; would have been a surprise to his business friends in the city, indeed.
"There's the Parrot!" cried Scrooge. "Green body and yellow tail, with a thing like a lettuce growing out of the top of his head; there he is! Poor Robin Crusoe, he called him, when he came home again after sailing round the island." (2.57-59)
The fact that little Ebenezer reads fantasy fiction rather than history or biography as a child is meant to be a tip-off about his eventual transformation, don't you think? If he was willing to buy into it then, he'll probably be able to buy into it again really soon.

"There's the saucepan that the gruel was in!" cried Scrooge, starting off again, and going round the fireplace. "There's the door, by which the Ghost of Jacob Marley entered! There's the corner where the Ghost of Christmas Present, sat! There's the window where I saw the wandering Spirits! It's all right, it's all true, it all happened. Ha ha ha!" (5.8)
Look how far away from rationality and logic we've come—Scrooge's proof of the reality of the experience is the fact that… everything is back to the way that it was in his house. Think about every movie that has the protagonist waking up from a dream only to find some element of that dream actually exists in waking life, and now compare that to this, where nothing of the ghosts remains. What in the world are we supposed to do with that?

It was a Turkey! He never could have stood upon his legs, that bird. He would have snapped 'em short off in a minute, like sticks of sealing-wax.
"Why, it's impossible to carry that to Camden Town," said Scrooge. "You must have a cab." (5.32-33)
Scrooge's powers of logic are now entirely bent in the service and economic benefit of others. Check out how instead of shrugging his shoulder at the difficulties faced by others (as he had when he said that the poor should be satisfied with jail, the workhouse, or death), now he uses his resources to solve the logistical problems in front of him. Would this kind of thinking work on a larger scale though?
