Oddly enough, this very blog post is the only Google result I get for the quoted phrase. Anyway, the thing looks inkblotty and fractally enough that I could plausibly mistake any frosty island for it in a dream. Probably related to the fact that we regularly have déjà vu in places of which (we think) we’ve dreamt. Or at least I do.
I got one layer deeper. I googled the same thing, but I ended up here back at HN because this very conversation has already been indexed and is now a top search result.
