Saw object at very close range next to residence hovering. moved very rapid and sent out bright blue flash and vanished into night sky.As I pulled in my driveway I seen different colored blinking lights and thought it was an airplane but realised the object was very close to my roof of my residents hovering.Immediately lights turned off and object moved fast as lightning diagonally back and forth a few times. Released a very large blue flash that blinded me for a second as if a picture was being taken of me. After the flash, I could not see where it flew away to. Vanished in the night sky.
