I don't question that you have been subject to a recurring dream, and no doubt it has a background vaguely similar to this. It would be quite enough to account for your feeling that you've been here before, it's quite a common experience.

- Can you describe this late arrival?
- It's an attractive girl with dark hair.
- Is that you can tell us about her?
- She comes in quite unexpectedly, and says something about not having any money.
- How romantic. Do you fall madly in love with her, Mr. Craig?
- Have you ever told anyone about your dream?
- In fact, there's no evidence you ever dreamed this dream at all, is there?
- None whatever. I haven't a scrap of proof.
- Personally, I don't need any. I believe what you say, Mr. Craig.
- I believe you really have dreamt about us all.
- So do I.
- Me too!
- And that's all there is to it?
- You never know. Perhaps it's like the Red King's dream in Alice Through The Looking Glass.
- None of us exist at all. We're nothing but characters in Mr. Craig's dream.
- That's right, and when he wakes up, we shall all vanish into thin air.
