I remember that it was about a boy who kept drawing a mysterious guy in black and had visions in his room and he saw drawings on the walls, he kept wondering who the mysterious man was and somehow knew that the visions he kept drawing were going to happen and that the man in black was coming for him because he knew who the boy was. I also remember he had a female friend.
Any chance it is
“Knowing” (2009)?
