There’s a scene in the 1963 film “The Haunting” in which something comes down the hallway of a haunted house one night. As two women huddle on the bed, a deafening, powerful pounding begins on the door to their room. Then, in a truly creepy scene, the pounding stops and, in absolute silence, the door starts to slowly bow inward, as if there is a tremendous pressure being exerted on it from the other side. Ultimately the door holds and whatever is was that came down that hallway moves on.
I don’t remember everything about that film, as I saw it a long time ago. But that scene in particular has always stuck with me. Perhaps because it was the first time I ever realized that the unknown and unseen could be more frightening that the known and seen.
