Hard to tell the difference between ghost "stories" and stories of ghosts. There are some very good bloggers who have a special gift with ghost tales. Anita is one of them. I like this story because it originates from Hawaii...and it is about cats.
Took another photo with a disc anomaly. (You'll find it to the right of the stack of wire crates and above the photo.) I need to find someone to submit these to as I seem to keep having discs in the photo. The camera, batteries, and memory card new.
The locations do have a certain energy about them; and some have a well-known history but, of course, there is nothing anyone can prove except to note they have had a certain experience or sense of the place when they are there. Not much science to work with.
Someday it might become more clear as to what creates the disc effect in my photos. For now, it looks a bit large to be dust and we can't really say what it is until we rule out what it isn't...
