I have some ideas:
The character is running down a hall from the entrance, opens a door and walks through. They walk back out and the hall changes so that the entrance is now the kitchen. Lets say you walk down this hall a ways trying to find out where you are, and you see a ghost and you avoid it by going through a door which leads back to the hall you were just in. When you try to open that door, it's jammed. You take out a weapon to defend yourself, but can't find it, and when you do your aim becomes more and more erratic as the ghost approaches nearer to you. As you finally do get your aim straight, the ghost disappears and the musical cues signaling are gone. You continue down the hall when the music returns. You search for the ghost and a door slams. The music fades. You walk further down the hall, and stop to look around, but the sound of footsteps doesn't stop until a second after you do. There is no music. In it's place, the sound picks up slowly as whisper that becomes louder. Suddenly there's a musical cue for the enemy, and you prepare your weapon. You look for it, but it's not there. It suddenly goes quiet again, and all you can hear is one final whisper before fading back to normal.
As you continue to explore the house, you occasionally hear doors open and close in the distance. You see indistinct shadows move around corners. Under the cracks of doors are bright lights. There are voices of many people. You step through, and you find an empty and desolate room. You explore the room. There's a dining table set with plates. You turn to leave, and one of the plates crashes to the ground. You turn, and see a shadow fading away with a face of a child looking up at you. The eyes close and the shadow is gone.
