In The Strangers, one of Halloween’s latter day descendants, the victims ask the three killers their motive. One answers, “Because you were home.” The home, therefore, brings the danger as much as it insulates us from it.
While it is generally true what Bachelard claims—namely, that “the house shelters daydreaming, the house protects the dreamer, the house allows one to dream in peace”—the fact that we believe this wholly, that we allow the house to become a sanctuary in our minds, that we let down our guard in the home, is not only what can turn those dreams into nightmares, but worse, it is what can wake us from our dreams into the worst form of nightmare: a living horror.
