I love horror movies and ghost stories. At first glance this seemed kinda cool... then I thought about actually having to live there. So annoying!
The story is this family, somehow, is receiving an AM radio signal through their wall. Something in the wall is acting as a speaker, and they can clearly hear talking and music.
Dang, I feel back for them! Hopefully since this story is getting picked up online now, someone who knows how to fix the problem will reach out to the family.
