Do you think the possible Skeletor Hampton Court ghost sighting was just an actor?

There are no sightings of supposed human spirits, there are demon spirits, which are all over the world, and sometimes they take the form of people who were on this earth, to deceive those who knew them.

Simply put - a hoax

It is much more likely to be an actor than a ghost since we know actors really exist whereas there is no good evidence for ghosts being real. 

As someone pointed out on youtube - so a ghost knows how to close modern fire doors with bars?  Looked line someone wearing a long coat (maybe long dark coat with lighter band around the edges).
