Remained Unanswered
There are some questions that are still left unanswered. Did he really felt something that day? Or was it all in his head? If Christopher’s mother sold the house, did the other owners had the same experience? A hidden mine inside the property that nobody knew of. A secret room which had text “FOREVER” written on the wall, who did that? We don’t know if anybody ever again entered that mine but whatever that thing was, it should be checked. If that mine is really haunted then people should be aware of that so that no one ever goes through the nightmare Christopher did.
