The Follower Trilha sonora (2017)

Internet video blogger David Baker is invited by Carol, an eccentric and lonely woman, to investigate supernatural occurrences in her home. He is instructed that he is free to film everywhere except for her grandmother's room upstairs. At first, he sees nothing. However, things take a ghostly turn as he slowly discovers that things aren't what they seem and, even worse, it could be that something wants to follow him out.
