Great idea!

Why leave hallucinations to chance? ;) The prompt could tell ChatGPT to randomly insert several authoritative sounding but verifiably false facts, to give the students debunking challenges! That solves the problem of GPT-5 being too smart to hallucinate, while still leaving open the possibility of talking rats.

What you're envisioning reminds me of Timothy Leary's Mind Mirror, published by Electronic Arts in 1985 for the Apple ][ and other home computers:

>Players answer questions that, when churned by Mind Mirror’s cryptic algorithms, can allegedly help them reveal intriguing new aspects of their psyche. Gameplay predominantly revolves around defining, comparing and then role-playing through different personalities in various text-based life simulations.

I extracted all the text from the Apple ][ Mind Mirror floppy disk image:

Just for laughs, here's ChatGPT's summary of that file, and its answers to questions about Timothy Leary -- I sure hope it's not hallucinating:

What's interesting is that game was based on Timothy Leary’s PhD dissertation “The Social Dimensions of Personality: Group Process and Structure”, which he ultimately used to break out of jail.

Before he got into LSD, he designed the Leary Interpersonal Behavior Circle personality assessment, which laid the foundations for understanding human personality and interpersonal behaviors.

In the 1970s, Leary was arrested for possession of marijuana. As part of the intake process, he was given a psychological assessment designed to gauge the risk of escape or violent behaviors in inmates. This test was known as the "Group Psychological Assessment Test." Leary was familiar with the test – having designed it or at least aspects of it. Understanding the criteria being measured, Leary answered in such a way that he was categorized as someone who posed a very low risk of escape or violence.

As a result, he was assigned to a minimum-security prison. With the lower level of security and his connections, Leary managed to escape prison in September 1970. His escape involved various affiliations, including with the Weather Underground, a radical left-wing organization. After his escape, Leary fled the country and spent time in various locations, including Algeria and Switzerland, before eventually being recaptured in 1973.
