He's no more psychotic than small children who went to Disneyland and met Mickey. What Chris has is a
fantasy-prone personality as a consequence of his :autism:. He makes shit up, then lives in his augmented reality.
Many mental problems involve believing various falsehoods, and psychosis covers a particular type of false beliefs - narrow, acute, intrusive, and not actively made up: "all purple objects are alive", "lamp posts are secretly giraffes", "my head is connected to the sky with wires and I should count my turns and untwist the wires
or else". Then they
might cast about for the justification and accommodate it into their daily reality; for example, a psychotic who believes he's being targeted by the government can suspect various people of being government agents, disguise himself, evade pursuit, vary his schedule to avoid assassination attempts, congratulate himself on stayng alive, come up with a (((theory))) on why he's being targeted and post about it on the internet. But he won't make shit up about him infiltrating a secret government laboratory, hijacking a plane, rescuing the president from terrorists and fucking 72 supermodels in the butt if he's actually been in mom's basement all that time. (Or they
might not: oops, that's 450 degrees, danger zone! spin counterclockwise once, pet the giraffe and walk on.)
Religious psychotics wake up in the middle of the night suffering from sleep paralysis and can't come up with a better explanation than demon rape, religious schizoid fantasizers write porn about themselves while furiously masturbating instead of going out and getting laid because good girls wait until marriage.
