I read his website, we studied those individuals in my psychology class last semester during halloween.
The instructions were to find an explanation that would make them the victims of a psychological operation.
Some of my class mates said: That some dead entities that passed away in a mental facility near his home with multiple character syndrome, want to possess, gobern or deceive his mind into joining them when persons judge him as crazy.
That the reason he talks about all those fictional roles, is because the fugitive crazy dead entities are trying to hide in his house while they act out different costumes with the intentions to try to make themselves sound important to distract from the intrusion.
They invade his personal space and confuse his character personality that distinguishes him as a person, by whispering back at him in echoes what their presence provokes him to say.
Then they try to haunt him into thinking that they are mimicquing, cloning or stealing his identity, because they are trying to manifest themselves, when they scare him through the nonsense that he uploads when he pleads for help.
I read his website as you asked and hope this helps in explaining his behavior, Dear Sir.
