I downloaded this and I cant make any sense of what Horn is babbling about.
If you look at the tone, And the Suggestion of the article at the subject here, you will notice this person is a classic paranoid schizophrenic, Right down to the disconnected incoherent speech and auditory hallucinations.
I took psychology for a great while, One common wisdom is, If it clops as a horse gallops like a steed and nays like a mustang, It's probably not a rhinoceros. one would be hard-pressed to subject the article to psychological scrutiny and not determine paranoid schizophrenia.
I mean, I believe there are things out there we don't understand. I believe intelligent life forms from other stary systems may have once visited earth, But I also know insane people do exist, And Horn and Billy Meier two peas in a pod.
