A name for it.

I found out there is a term for the type of speech the zombies use in "The Hortlak." It's called word salad, and is seen in patients suffering from severe mental disorders. (I wonder if that says something about fantasy writers, or readers.) I found this interesting as it supports the general pattern in Kelly Link's stories of the dead suffering from a sort of degenerative mental disorder. Not really useful for my topic ideas, but maybe someone will find it helpful.
