Anomalies in the laboratory

While waiting in the waiting room, Emily hears the sound of sirens in the distance. However, she did not pay any attention to it and just sat there. Soon the sirens stop and silence returns. A few minutes later, she hears the front door of the hospital open. Emily looks up and sees two uniformed police officers talking with Sarah, the receptionist. The policemen then headed toward the examination room where Luna was. Emily got up and went to the examination room. What the hell is going on?
