The Forest — one of 2016's up-and-coming horror films — hits theaters on Jan. 8. It tells the tale of a woman (Natalie Dormer) who goes into Japan's legendary suicide forest, called Aokigahara, in search of her lost sister. The film paints a haunting portrait of the sacred grounds, which are filled with ghosts and hallucinations, but what's the Aokigahara Forest like in real life? To prepare for the film's release, we recently interviewed the film's star, Dormer, and she shared details from her own personal experience. Read on to see what she said, then check out everything she told us about Game of Thrones.
