Old Lady Ghost was noted to have haunted Erin as a girl. The ghost is referenced in 2016 movie.
Erin at age eight encountered a nightly haunting by a recently passed away neighbor. The mean old lady would appear at the foot of her bed every night for nearly a year.
Because she was not believed by her parents, she went to therapy for years. When her classmates found out, they started calling her "Ghost Girl". Abby was the only one back then that believed her story.
