Deceiving Doppelgänger - Entity Plays A Trick On Dad

Dad was sitting at his computer. He hears the stairs door and someone coming down the stairs and he sees Kayleigh carrying a box with a camera light in it that Dad had asked Kayleigh for earlier.

After Dad takes the box, in return he passes Kayleigh a tin with some spare metal model parts in it that Kayleigh wanted back.

Dad turns back to his computer and as he does, the tin crashes to the floor. When Dad looks back, he does not see anyone standing there!

Instinctively and from past encounters, Dad knows that this was the entity appearing to Dad as a Doppelgänger of Kayleigh!

The camera shows no one, but Dad saw and heard Kayleigh as if she was the real Kayleigh.

Dad calls Kays downstairs and tells her what happened, and just for arguments sake, has her confirm it wasn't her playing a trick...although she'd have to move faster than light to pull this off!
