All that surrounds us—sights, sounds, colors, music, words, fragments of conversations—penetrates our minds to some degree and is turned into something else. Think of an earthworm’s castings, which are the product of what passes through its body to be transformed into something new and enriched, or at least different from what it was. The process happens whether we’re aware of it or not, and it’s beyond our control. As Stephen King once remarked, if you eat asparagus tonight, your piss is going to smell funny tomorrow,

It’s one of those stories that started from like eight different directions at once. I had to put it together like a puzzle, one piece at a time. I remember sitting in a friend’s kitchen in St. Paul, working on the middle section, so it took a long time to do. Sometimes the stories I like the best work out like that: they don’t have a concrete beginning. They’ve just always been with me.

I think trucks and the desert are firmly entrenched in the Australian psyche. My husband used to work for a drilling company and drove road trains (three trailers) full of drilling equipment between work sites all over Queensland and South Australia. He’s got some crazy stories from that time, and I just write them down. I’m sorry to say the exploding cow is a true story. And his window was open.

Stories of terror and wonder are an escape from reality, but also another way of looking at our own existence, dealing with our emotional needs. Ghost stories, for instance, can be metaphors for the way we deal with our unease with death. Tales of magic are the way we fulfill the very real human need for wonder.

I’ve had an uneasy relationship with this genre, because I think there’s something very racially essentializing about the classification of ghost stories as horror. Dead people are part of my daily life, as they are for many nonwhites practicing traditions of ancestor reverence. So my Asimov’s SF story “The Rainses’” (which was reprinted in Filter House), for instance, never felt all that scary to me. But it was for some readers, because of the ghosts.
