Ghost Houses?

Of course (like you?) I am always interested in ghost stories.  There are so many types of hauntings!

A recent find made me think that perhaps when I eventually begin to write my book about true Maine ghost stories (yes, it's in the pipeline, behind a couple other ones!), one chapter should be about Maine ghost houses, as it appears there is more than one.  

What do I think of as a ghost house, as opposed to a haunted house?  A ghost house is one that reappears in its prior form, as the ghost of what it once was, where only a ruin of itself remains now.  This occurrence is uncommon, but occasionally some unwitting person is there to witness it happening, and that is how the rest of us find out about such otherworldly things.

A good example of this is Chapter 10 in Carol Olivieri Schulte's Ghosts on the Coast of Maine, titled "The Invisible Estate," set in Northport. 

If you know of any local Maine stories about a house that isn't there... until sometimes it is! ... please do drop me a line.  I'd love to hear about it.
