There is no solid evidence available as far as I know. Anomalies and strange phenomena yes, but no valid evidence of paranormal phenomenas ever caught. 

That's why people keep "hunting"…

Personally, I don't believe we yet have a valid theory or methodology that allows us to catch any evidence, and the pseudo-science (EMF etc) of later ghost hunters is not helping, even if that is what is intended. In my opinion, we need to return to the drawing board…

So far, the St. Augustine Lighthouse seems about the best that we have so far, at least as per what GH has shown us.

The most impressive, though far from conclusive, proof that something is going on comes from Prof. Wiseman, almost a non-believer in things ghostly.  But his excellent experiment in Edinburgh's famous vaults has even him scratching his head.  He doesn't admit to paranormal activity, but his viewpoint is that something is going on with us, perhaps psychologically, under certain conditions.

You might like to read about it here.  This is, as far as I know, the most scientifically bent experiment carried out so far.  Now he was on the right track!

Has anyone ever explained the figure caught on video dressed in period costume opening a door at an English castle/tourist attaction???

It was a few years back and I saw it in the news section of yahoo. If real– pretty darn creepy and amazing.

Yes, unfortunately the figure was all too human.  I don't have the link to the explanation since the guy came forward years ago and told what happened.

He was an employee at the castle who was dressed in period costume.  They were instructed not to leave their posts but for a reason I can't remember he went out a door covered by a security camera and was caught.  It didn't have anything to do with trying to fake anything; maybe a potty break?  I simply can't recall.

He kept his secret for quite a while for fear of being fired but due to the furor that this raised he finally came clean.  And that was the end of the ghost in period costume.

Bummer.

P.S.  I am trying to contact a fellow in the UK who runs a debunkers' site about this.  Hopefully he can fill in the details.  But it's been awhile since the confession so I don't know if he will recall it.  If he does, I'll post his answer here.
