Ghost Ping...
It looks real to me...don't see what else it could be.
That gave me a goose bump or two.
That corridor looks exactly like the downstairs basement of the Lockwood Matthews Mansion in Norwalk, Connecticut.
Why is that? It was used in the old film "House of Dark Shadows" back in '70. Even though that part wasn't used in the film, the corridor has an eerie resemblance of the downstairs basement of "The Old House" on the old Dark Shadows soap.
Remember that, FF? :)
