Yes, because they can see past the veil. But in my view schizophrenia is a spectrum like autism. Some are so broken and have a hyper ego, so they will craft their own veil to put over their eyes as a way to cope. Some can't even understand spiritual and only attack material evidence things, and cant perceive something unseen. I have worked with many 'schizophrenics' and most of them did not have to conspiratorial mind, they were just broken and really paranoid. I noticed that most will tell you story's about how they were victimized and play the hero role, and they will have no filter and will jump years between events of the story.

Also schizophrenia is a label that the normalfags, and the archons use to dehumanize anyone who can see. The government isnt the only thing spying on people, I think the system itself is in the minds of everyone and will corral people based on their thoughts.

I noticed if a normal person starts to think for himself, the reality will swiftly 'punish' them. Like they will hurt themselves, or some other stress event will arise to distract them. It will do it my case, but will use different tactics because Im aware of it.

Schizophrenia is an inducible disorder. It only takes a single injection to alter someone's immunoresponse so that their nerves fray apart and start overlinking. Immune-modulated damage to myelin sheathes is the actual causality of schizophrenia. An RNA injection can sensitize the immune system to myelin proteins.

Mind-reading has already been rolled out IRL. Flat Earth was a research meme rolled out to test the experimental victims of the mind-reading program and learn what the subjective experience of believing retarded disinfo was like. The idea was to prevent future primitivism by learning how to control minds so future generations (of mind-reading victims) wouldn't believe in flat earth.

Schizophrenics were also targeted by mind-reading research, to 'find out how to help people'. This 'helpful' program was an easy dismissal chute for undesireables as the program was compartmentalized such the rational, compassionate researchers were not informed that schizophrenia can be induced.

I think the angel and devil on one's shoulders metaphor is quite accurate. So much so it makes me question who came up with that metaphor? Of course they're not literally on ones shoulders, but in the non-physical space where your spirit resides. They can hear you, you can hear them, but they're not always aware of you, and you're not always aware of them. Swedenborg says talking with them can be just as dangerous for them as it is for yourself, because some of those spirits simply aren't ready to deal/cope/understand or whatever the reality. I think this is true for many 'normal' humans too, which is why the 'veil' exists. 'Normal' people don't differentiate between these outside forces and their own thoughts when or if they hear them. The belief that hearing voices makes you schizophrenic has reinforced this. The evil ones work together the downfall of man because they hate them. Hate is what they'love' to do. They will whisper evil things to people in an attempt to manipulate them. I think maybe it's sometimes very subtle, like giving people certain feelings, but at other times it's much more obvious like the Agent Smith effect. If someone is particularly vulnerable they could even just take over a person temporarily. 
I think if you are truly and sincerely pious, not necessarily or unnecessarily in a religious sense, but mostly in a spiritual way, the good spirits will notice it and may help, guide or protect you. Again, some people kinda need these beliefs, so taking that away from them may not be a great idea. Same goes for spirits too.
