It is strange. Really! Its strange why it starts in the English language and finished in the Russian (?) language. Also, at the critical moment the camera takes pictures of the ground. I have no way to slow this clip down to view it frame by frame. If the dog runs to the floating girl, where is the dog? Then you hear the dog bark and the camera takes picture of the snowy ground and the next time you see the girl she is in the woman's arms. The girl is than put on the ground, they both run away and more pictures of the ground.
Somewhat convincing but a lot of room for doubt. Just my opinion.
