Quote context

[...]

- Guess what I dreamed I saw coming over out of the woods?

- I haven't the faintest idea. A skunk?

- Well, sort of. It was Mr. Connor.

- Mr. Connor.

- Yes, with his both arms full of something.

- And guess what it turned out to be?

- What?

- You and some clothes.

- Wasn't it funny? It was sort of like as if you were coming from the pool.

- I'm going crazy. I'm standing here solidly on my own two hands and going crazy.

- Then what?

- Then after a while, I opened my door a crack, and there he was in the hall, still coming along with you, puffing like a steam engine.

- His wind can't be very good.

- Then what?

- Then you were sort of crooning.

- I never crooned in my life.

- I'm only saying what it sounded like.

- And then he... Guess what.

- I couldn't possibly.

- Then he just sailed right into your room with you, and that scared me, so I got up and went to your door and peeked in to make sure you were all right. And guess what.

- What?

- You were. He was gone by then.

- Gone? Of course he was gone. He was never there.
