In fairy tales and movies, the forest can be a scary place (think of the Big Bad Wolf, the Blair Witch and other woodland ne’er-do-wells). Once we leave childhood, most of us stop trembling at the thought of being lost in the woods and being at the mercy of evildoers, but for an unlucky few, even a short forest hike can quickly turn to horror with imagined wild animals and serial killers lurking behind every tree. For a small subset of hylophobes, the terror is particularly bad at night and is called nyctohylophobia.
