If this was a real event, I'm curious how this would be possible

The longer version shows it rotating half of it's body along an axis around three different times. After it does that, the video here shows it looks to be an organic body because it morphs/opens into an elongated oval shape before seemingly closing and warping out of existence. Assuming what happened was a real event, I'd say that the sequencing leading up to the disappearance into thin air was a preparation sequence to go back to wherever it came from. My mind can't comprehend how this would...
