Here's an example of not knowing what you're doing with a camera. But since I do, I'll explain what happens (this was produced intentionally by me). This looks like maybe an energy ball (orb) smashing into the wall after zipping around the room a bit. What causes this on digital cameras (and even on film cameras if you don't pay attention to your settings) is setting it to night shot mode. While this is on most cameras, it is not true nightshot (such as infrared). On the non-infrared cameras, nightshot works by prolonging the expsoure setting until enough light is absorbed to make a picture. I simply took a picture of a night light (seen on the wall in the picture below) and moved the camera to the computer desk area within the time the shutter was opened. This does not happen in auto mode, or flash mode, only in the nightshot mode. Be careful of your settings on your camera as this can lead to false conclusions.
