The claim that the Beings inevitably create cultural and psychological alienation as a deterrent or retaliation, manifesting as paranoia or even paranoid schizophrenia (delusions, hearing, seeing, compulsive thoughts, etc)....
Is indistinguishable from the actual psychological state from you, OP, simply being paranoid and/or mildly schizoid
I can say this because I am mildly schizoid, and you have to remember that these experiences and feelings are not real if they are not falsifiable.
Use falsifiability as your compass and you will find that not only are there no Beings to speak of, all of the effects that you attribute to them are manmade. The cultural and psychological alienation is simply an effect of being immune to the current levels of propaganda. It's like travelling in the opposite direction of everyone else, it's not an external manipulation or supernatural, this is simply what it feels like to be "Alive in One of Those Times". Nietszche felt it, many great thinkers throughout history know what it is like to see through the illusion of the State and the Popular Culture.
"And the abyss stares back."
