As they tried to leave, Emily's books and papers began to scatter across the floor. Lily bent down to pick them up, but Lucas grabbed her arm. "Wait," he whispered. "Do you hear that?" A low hum filled the air, growing louder by the second.
The room started to shake, and the lights flickered ominously. Lily's heart sank as she looked around. Suddenly, Emily vanished. One moment she was there, the next she was gone. Lily and Lucas frantically searched the room, but she was nowhere to be found.
"Emily!" Lily called out, her voice panicked. There was no response. The hum grew louder, and the room shook harder. Lily and Lucas exchanged a terrified glance. What was happening? They were frozen in fear, unsure what to do next. The silence was broken only by the hum.
