Horror movie with hallway scene

I overheard a guy talking about a horror film while I was riding the bus. He said there was a scene in the movie where two people were walking down a long hallway while holding hands. All of a sudden, the hallway goes completely dark. The two, while still holding hands, were talking to each other to make sure they could hear each other’s voice. But when the lights came back on, each person were at opposite ends of the hallway, while holding hands with a “demon” or some other evil person/being/creature.

I have no idea about the name of this movie.

Got something to say?
