Pygmalion’s delusion

A belief that a chatbot, LLM, or other AI has gained sentience or "become real" coupled with intense feelings for it, romantic or platonic.

capgras delusion

Perhaps the most fucked-up disorder to ever grace this planet. It's when someone holds the delusion that someone they know—a friend, relative, spouse, pet, anything like that—is replaced with an identical imposter.
Discovered by psychiatrist Joseph Capgras (who is also the namesake of the disorder).

The capgras delusion is terrifying.

Targeted Harassment that mirrors the delusions of reference

Is what I actually said, though, it doesn't even take that much to justify killing any of you.

Hym "But the targeted harassment that mirrors the delusions of reference that violates both harassment law and likely school bullying policies and sometimes stallking laws and/or violates the privacy act of 1974. But yes. I would gladly murder your kids over it and CLEARLY other people agree. AND! AND... We're winning the war on weaponized schizophrenia at a ratio of 10 to 1. So, yeah. Entirely avoidable child death. Caused deliberately by YouTube internet pundits whose lives need to end as quickly a humanly possible."

Liv delusion

a very specific brand of delusion. this is where you dated someone who dumped your ass, then you go on acting like they didn't. this includes posting about them on social media with captions like "loml" and texting them asking when your next date is, when honestly they probably blocked your number.
if left untreated, you will likely end up throwing your entire life away for this person, failing your ACT and never going to college because all you do is think about them. therefore, it's best to seek treatment as soon as onset of symptoms begin.

1: did you see Amy's latest insta post? still posting about Ethan and her anniversary even though he dumped her ass
2: oof she got that Liv delusion. someone better save her before it's too late
