I’m trying to pull out an old movie memory…Mystery, Thriller, Drama

A family who was moving to a new house and on their way up the hill they were ran off the road and they crash. The family gets out of the car and walks up to the house. There was a man there that tells them about ghosts and how if ghosts try to make phone calls they will only hear static etc. he is the only one who knows they’re ghosts. Anyway all this stuff is happening to them and they finally decide to leave the house and as they make their way down the hill they find the crash site and realize they’re actually ghosts.
