Remember in the American version how when she was in the hospital, they asked her how she made those pictures? And she said, "I think of them, and they appear" or something similar? Well, the tape was found at the lodge under which she was buried, where her mental powers were the strongest. I guess we are supposed to think she thought of it, and it appeared to lead the reporter to the well so she could "release" her and make her more powerful so she could get her revenge or whatever.
