Adria Barich is a haunted woman. Her tormentor tracks her everywhere, threatening to ambush her in a dimly lit parking garage, as she drives down a desolate road or when she's let her guard down to wash dishes or collapse on the couch.
"I've actually changed my ringtone a few times, because I start to associate it with terror," says Barich, a 24-year-old California woman who works in marketing. "But every time that I do, after, like, a week or so, it just becomes terrifying again."
