Russia
Investigation Summary
In early 2016 a viral security-camera clip said to be from a Moscow bar circulated online, appearing to show chairs, curtains and a hookah pipe moving in the empty room; staff reported knocks and lights switching on and off, and owners reportedly called in a paranormal group. The footage is single-source and unverified, and such clips are often hoaxes. Recorded by PRN as a reported/folkloric case — historical context, not proof.
