I have a theory that only lesser demons can realistically possess humans. I suspect demons cannot enter a soul, but merely wrap themselves around it and contain themselves within a physical body. If a demon is vastly powerful, a human body is not enough to contain the demonic presence(s). This has made me wonder if powerful demons can divide themselves between various bodies and possess a collective group, or what manner of demon may prefer the bodies of extraterrestials. Imagine how powerful a demon would be in the body of an alien lifeform. The implications of this may be horrifying to you.

My theory is that everyone is already possessed but the demons will only manifest if you try to get rid of them, any successfull exorcism attempt will get very close to the destruction of the body.

I also think that just one demon can posses a unlimited amount of people, they would not enter into the soul but rather put a seed at the very center of it, and with that seed they could control people, corrupting memories, perceptions and everything else.

Saying that every person is possessed is mildly accurate but untrue more like in the modern age more people are possessed than normal due to sciences declaring exorcisms and demons don’t exist and as such possessed people are just seen as crazy. But not all people are possessed. And one demon cannot possess multiple people as they use a person like a vehicle so they can exist physically in our plane of existence. The fact is that remote controlling humans isn’t viable because there’s no real reason to anymore. Controlling large swaths of people has an appeal but there’s so real reason to do so because a demon would gain nothing from human materials
