Our friend Ken shares a nesting box of a dream:

In the dream, you told me that you really liked a word I had coined. I responded that I wasn't surprised, because you'd actually coined the word yourself, in a dream I had (which was a dream within the dream I was in).

Here's a list of the levels:

1) Ken writing this e-mail to Craig describing
2) A dream I had, where you were impressed with the word I'd coined, where I said that
3) I'd had a dream where you had coined the word, and told it to me.

Make sense?

Unfortunately, I don't remember what the word was...
