Somewhat inspired by Psychonauts, in the sense that the IT + Adachi are psychic with the powers you learn in PN and it takes place at a summer camp (not a psychic summer camp. just a summer camp).
The IT all attend a summer camp that’s being hosted by the school. Morooka is a counselor as is Adachi. Mayumi died prior to this camp starting and that’s why Adachi is there (instead of the camp just being canceled). Several Social Links are here too since it's for all three years, so Naoki, Kou, Daisuke, and Ai are all wandering about the woods. Saki is there too but she ends up dying not long into the camp. Adachi manages to somehow convince Morooka to not cancel the camp (they end up burying Saki somewhere in the woods), and Morooka probably doesn’t die since Mitsuo isn’t here at the camp. I can't tell if that's worse or better than him dying.
The IT are psychic, the camp itself isn't, the IT are just all conveniently psychic. Some of them knew from a young age and hid it, others found out not long before camp started. Adachi is also psychic, he most likely used telekinesis or something to murder Mayumi and Saki so there’d be no trace of him killing them (he didn’t use his confusion power because he wasn't aware of it until after Saki’s death). Yu has a PSI-Door (don’t know who he stole that off of, maybe Adachi dropped it and Yu didn’t know it was his so kept it?) and uses it to reverse Adachi’s confusion bombs on the campers.
The Mental Worlds = The TV Dungeons, the hub world/general TV World is the Collective Unconscious, but it looks a bit different than it does in game (it's not like a brain and a bunch of doors its like a platform with a bunch of different pathways leading from it). Yu and Yosuke encounter the CU during a strange dream/accidental projecting into it and meet Teddie. Teddie just kind of “guards” the CU, looking pretty much like he does in canon (side note, everyone looks like they do in canon, just instead of wearing Yasogami uniforms they wear camp shirts and shorts. When Teddie comes to the real world they steal spare clothes for him). Teddie doesn’t need a PSI-Portal to enter people's minds, he can just Do That, and it kind of scares the others. I don’t know what all he can do besides that and a few other things, but I think it would be funny if he was just “new power as the plot demands” because he got laser-beamed in the head with psitanium/silly (as well as being an actual resident of the mind).
Not long after meeting Teddie, Saki is suddenly killed, and after a small funeral service, the camp goes on. Rather than the IT being kidnapped and thrown into a TV, they are put into a state that nears unconsciousness (though they're still there enough to give consent to mind-entering), and can only be snapped out of this by a person entering their mind and resolving the conflict or whatever. It's something Adachi can do (it’s some sort of PSI-Power he has, perhaps a personally altered dangerous version of the confusion power?), and if they're not snapped out of it before a certain point, they just fall completely unconscious and can’t be woken up.
Chie initially stays by Yukiko's side when it occurs to her, but she overhears Yosuke and Yu talk about the PSI Portal and asks to come with them once they get Yukiko's permission. This is when Chie meets Teddie. After Yukiko it’s Kanji, then Rise, Teddie somehow comes to the real world, then Naoto. Since Teddie has the ability to enter minds without the need of a PSI Portal, he just realizes it works both ways and uses it to dip out of the CU. He’s also gained a human body, as well as clothes. He doesn’t initially have access to many PSI Powers until he wanders off day one of being in the human world and encounters a Bit Too Much Psitanium. Whoops!
There are a few things Teddie’s capable of doing prior to this incident – such as teleportation, telepathy, telekinesis, and mind reading. The rest of the powers are unlocked by the psitanium. Despite Junes not being a Thing here (I mean within the plot, it obviously still exists) Yosuke still basically takes Teddie in, letting him stay in the empty bunk above his own in his cabin and being the one who supervises him the most. Naoto is still suspicious of them, since everyone who was snapped out of their confusion induced state becomes a part of Yu’s friend group, but quickly figures its not them because it doesn’t makes sense (though she’s still quite confused on where the hell Teddie came from)
Teddie is a censor that became his own person and managed to leave the original mind he came from, and started hanging around the CU (especially since becoming his own person meant the censors from said mind kicked him out). He has his identity crises, but figures out who and what he is over the course of the game.
Dojima comes to visit around the end of the camp (he is not aware of what's happening because of Adachi intentionally making it so), where he and Nanako come to do some camp activities with Yu and his friends. Adachi uh. well. Because Nanako is so young, Yu and Teddie cannot enter her mind and therefore reverse the confusion effect that Adachi put on her, and so she falls into a coma-state. Camp is going great [thumbs up emoji] one teenager died and we all witnessed a six year old go into a coma.
When the IT finds out it was Adachi who kept confusion bombing people (because he was bored with the camp), they nearly kill him. They all nearly just use their PSI Powers on him and are only stopped because they can't risk getting in trouble for killing him. Besides, he needs to be alive so he can pay for what he did to Nanako, Saki, and Mayumi. Teddie has his breakdown alone with Nanako, which manages to remove the confusion effect on her (censors the damn confusion bomb like fuck you/silly).
Since he was originally a censor and is now no longer welcomed in his original mind (he doesn’t even remember who that was), Teddie isn't welcome in any mind. No matter where he goes, unless it's the real world or the CU, the censors will attempt to kick him out.
Yu most likely used his PSI to pass the time when his parents were out late, Yosuke tends to use telekinesis for work. Chie doesn’t really use hers much as she’s more focused on physical stuff. Yukiko once used pyrokinesis for cooking and nearly caught the kitchen on fire. Kanji raises plants as well as his sewing and drawing habits because of his herbaphony allowing him to connect to them on a deeper level than most people. Rise’s powers aren't really useful in the idol business but it's great to keep in touch with the others. Teddie can use his to communicate with the IT before he leaves the CU, which was... a jumpscare the first time he did it. Naoto’s marksmanship = firearm, she tries to not rely too heavily on her PSI during investigations, but it does help out
