Honestly, that's kind of how I see things: taking ideas/ingredients that I find interesting from all the toppings.
If I could, I would take targeted individuals: the fact that they manage to identify patterns in the interactions between people experiencing the phenomenon and other people, the fact that they are 100% convinced that it exists and is happening right now, the fact that they know antipsychotics aren't the solution, and the fact that, by coming together, we could make things change. Even though they are heading completely in the wrong direction, want to take the people experiencing the phenomenon to court, and hope for financial compensation.
From religions, I would take the fact that this is not new at all: religions talk to us about omniscience, omnipresence, peace, kindness, helping others, angels, demons, djinn, etc., who can communicate with humans through thought, through revelations, and so on. But then, paradoxically, and I’ll talk about this in another dedicated story, they also spread through violence, division, and the idea that one's own religion is better than everyone else's. From Christianity, I think Jesus could be a model for how to behave when people experiencing the phenomenon decide to interact with someone and we want to get better. From Islam, I would take the idea that Jesus was just one among many, and that it talks about the invisible world and djinn as something active. From Buddhism, the story of Yogi Milarepa and the demons shows that, in the end, demons do nothing once a person learns to control their emotions, etc. I'm not going to list all the pros and cons of religions and beliefs, but I think what matters is that ALL humans are just humans. There is no incarnate god.
And as for psychiatrists, honestly, I don't really know what we could take from them. For them, it's a 100% internal problem that can be solved with treatment. But paradoxically, it's supposed to be the best solution available today. But as I said elsewhere, I don't see how a medication could make it possible to stop hearing voices that contain information I sometimes didn't even know myself, or how a treatment could correct traumas, etc. Especially since these medications tend to cause a huge number of side effects. I even joined several Facebook groups dedicated to what people call “schizos,” out of curiosity. I read many very sad testimonies there, especially about the use of antipsychotics, which cause many side effects, and many people report having to combine several treatments that are supposed to create balance by counteracting one another's side effects.
