The Haunted House

You continue on, ignoring your reflection. Your friend, Katie, however looks sideways at her reflection and screams, "Who is that??" She is still screaming when she begins to choke. You finally look and there is a skeletal woman in the reflection choking Katie's reflection. She drops to the ground. The woman turns towards you. You quickly avert your gaze as you are caught up with the rest of your friends as they scream and run. You all manage to stick together. You can see the woman in the mirrors as you run. Your friend Lisa stops in front of you, staring at the reflection. She clutches her throat. A second later, you crash into her and you both fall. Everyone else keeps running. Lisa is crying. You are breathing hard. You get up, looking at the ground. She stays down.
"We need to go," you say. She doesn't get up.
