Gonna run this past people here and see what they think on this, but if I were in my room, looked out, saw someone dressed like that in the hallway, and I got lucky in that I was able to close the door and lock it without him hurting/murdering me, too... I'd sit there in complete silence probably until someone came to my room to either rescue me or try to kill me (the door's locked, I would call 911 if the person attempted to break the door down). Why would I do this? Because I'd be terrified the person was either still in the house or would return and noiselessly prowl outside the door and hear the little beeps the phone makes as I called 911. I wouldn't walk, I wouldn't want the floor to creak, there's no way I'm speaking on the phone even in a whisper. Why? Well, he probably didn't kill me because he thinks I'm asleep. If he knows I'm awake-- in that situation, I probably get killed. So I'm going to move mountains to make sure that person thinks I'm asleep. No dialing, no walking, no movements, no nothing.
