When I was a kid my entire family went on a vacation to Mexico. We’ve always had a scary, creepy, dark basement with a computer monitor down there. Also as a little background an elderly woman died in our house before we bought it and moved in. Anyways, when we got back from vacation I went on the computer to play on it. When I went on the computers camera roll, there was this 10 second video in black and white. The video starts with no one on the screen (even though you had to click the mouse to start recording), and plays for about 5 seconds until you the shadow of SOMETHING move across a window that is off screen. All you could really see was something interrupting the light shining through the window, nothing else. And then a few sec later the video stops. The video was taken while my entire family was in Mexico and the house was locked
