I was babysitting for my sister. At 3 a.m., her baby monitor lit up. I checked—her baby was asleep. Then a voice whispered through the speaker: “He’s not okay.”I called my sister in a panic. She yelled,“Take my son and run to the car. Lock it and call 911!”Turns out, she had also been hearing noises on the baby monitor, and it was freaking her out as well. Just then, as she was talking to me, I froze when I saw a shadow of a man pass by the window outside my nephew’s room. I walked closer and saw that the window was open

—one we always make sure to keep shut.I grabbed my nephew and ran to the car. When the police arrived, they searched the area but didn’t find anything. They told us that this specific brand of baby monitor is known for making “weird sounds,” and others had reported similar complaints in recent months.We replaced the monitor, and the sounds stopped. But I know what I saw. That shadow, that open window—it still gives me chills.
