"I went to investigate the noise and saw my treadmill was running. It didn't make sense because the treadmill requires a lanyard key to be reattached before it can even be started, which it was now. So, I checked my surveillance footage on my phone to make sure nobody was here, and I discovered this. As a result, I returned to my room, grabbed my pistol, and checked my house's rooms and garage to make sure nobody was there. I turned on the floodlights and looked outdoors but found nothing. I also looked at the time stamps and saw the light go off, and then, less than a minute later, she reappeared when my other camera detected motion."
