Unknown Entity

It was 2 weeks ago. Some of my family, (uncle aunt and cousins) were out in the backyard. I started taking random pictures of them. They wanted to see the pictures, but something uninvited was there. Orbs. Mist. That was never there when I took the picture. After research, it turns out that it wasn't dust or water, UFO'S. And no, I dont mean aliens. I suppose they are ghosts. Many pictures include the orbs, and it was always night. Even when we turn down the brightness to zero, (you cant see anything) They dont show up. Only at night. Although one picture amazed me the most, it was a humanlike object. It was leaning at the light. Its hand was extremely long, like a spider's legs. I still am looking for the USB wire to connect the camera to the computer. I need to upload the pictures. My phone does nothing at night. You cant see a single thing. Ill upload the pics as soon as I get the wire.
