To me, this looks like someone got trapped in a tree by a magicians spell. With Holloween coming I was looking for something scary, and this is the best I could come up with.
This unusual tree is on the Ringling estate in Sarasota, otherwise known as Ca' d'Zan. It's where John and Mabel Ringling lived and, now is a museum with sprawling gardens on Sarasota Bay.
This also reminds me of an Ent of LOTR fame. Of course, we have Peter Jackson's idea what they looked like; but before that, when I read the books, I imagined something like this. Maybe trees do have awareness, and we can communicate somehow. That would be a lot of fun, not scary at all. I'll look for something more frightening.
