The 13 scariest real-life haunted houses in America

Forget about those hokey attractions at amusement parks. There are real haunted houses spread across America.

We're talking about the true-blue, creepy-as-can-be haunted houses.

The houses where local residents claim they hear voices and where serial killers dumped their victims. The places that carry legends of entire families vanishing into thin air and serve as a backdrop for murders and suicides.

Photographer Seph Lawless braved these collapsing and dilapidated buildings for his new photo book, "13: Hauntingly Beautiful," to show us just how creepy these places really are.
