6.Mirror, mirror, on the lap:
A humanoid figure, without anybody, is something to be worried about. There are obvious signs of digits and legs, but where is the body? It’s not rocket science and this picture does not require any kind of specialist to decode. The man in the picture is basically holding a mirror on his lap, which reflects the stairway on the opposite side. Then why is the photographer not visible? Because he is at an angle which does not allow his reflection to fall on the mirror, making him appear invisible.
