If this is true, it wouldn't be the first time I have encountered incredible stuff that was written as fiction.
The Ketchi is a prime example. I read the instruction in Graham Masterton's novel "Tengu".
I found the Ketchi way too far fetched even for science fiction, so I figured I would volunteer to do one.
Knowing a Ketchi personally goes way beyond any science fiction story, because Ketchi have to be experienced to be believed and you would still have a problem believing, but there is no way you would ever forget the experience!
