The Light Vampire

The Light Vampire is an unknown, small creature capable of flight that expands and then condenses light from artificial sources.

Description
On June 17 2015, Youtuber TSpicer905 uploaded a video showing a time-lapse of his grandmother's neighborhood. During the last parts of the video what appears to be an unknown creature capable of flight lands on top of the nearest light-pole. Suddenly the glow from the light rapidly expands and is slowly pulled back in. A light in a neighbor's front yard across the road shows a similar effect.
