Paranormal experts are stumped by this mysterious video of a "ghost sighting" as an unexplained light orb travelled down a quiet residential street.

The strange light was caught on camera passing outside a house in the early hours of December 12 - prompting speculation it could be a ghost.

It appears from behind a parked car before quickly dropping to a lower level - prompting speculation that it could be a ghost.

Paranormal whizz Chris Romer, chairman of the Association for the Scientific Study of Anomalous Phenomena, said it was the best sighting of 2021.

Chris said: "It's amazing - it's a real mystery why the light dropped.

"It's some of the best footage I've seen this year."

But he added that it's probably not paranormal activity and is more likely to be someone carrying a mobile phone with the light on.
