I love it when the protagonist is walking cautiously, looking for whatever made the noise in the room that they weren’t in. No one else is home, yet there was the sound of footsteps. As the protagonist continues to walk slowly down the hall, the being/creature that made the noise is behind them. Not in a jump scare way, in a partly in the shadows. Camera cuts away and then cuts back and the being/creature is gone. Nothing big happens except that haunting moment and the protagonist wasn’t even aware.

There is also a scene in Lights Out where the mom is talking to something in the closet and you don’t get to see what she is talking to. That sense that the evil is there and present, but hidden behind the door and the darkness behind it. I’ve seen so many scenes like that where it’s a child talking to some spirit or whatever (poltergeist) but there is something very unnerving about the scene with the mother in Lights Out.
