Bonus Episode | Beyond the St. Louis Exorcism: What Real Exorcisms Actually Look Like

The St. Louis exorcism shaped what many people think possession is supposed to look like, but what do real cases actually report?

In this bonus episode of State of the Unknown, Robert Barber steps back from a single case to look at the broader question of possession and exorcism. Drawing on documented accounts and recurring patterns across different cases, this episode explores the gap between what people expect to see…and what is actually reported.

From behavioral changes and physical reactions to the influence of belief, media, and cultural expectations, possession cases don’t follow a single clear pattern. And once a case like St. Louis becomes widely known, it doesn’t just stay a case—it becomes a reference point.

So when similar experiences are reported again… are they independent accounts? Or are they shaped by something people already recognize?


🎧 In this episode:

  • What “possession” means across different contexts
  • The difference between expectation and reported experience
  • Why cases like the St. Louis exorcism influence future accounts
  • How patterns show up across unrelated reports
  • Where explanation ends—and uncertainty begins

Movie Possession Vs Real Reports

SPEAKER_00

When most people think about possession, they're not thinking about something subtle. They're thinking about the exorcist, the voice, the violence, the room coming apart. But when you start looking at real cases, the ones that were actually documented, it doesn't usually look like that. And that difference matters. And the difference between those expectations and what's actually reported is where this gets interesting. Because once you step away from what people expect to see and look at what's actually reported, you start to notice something different. Not a single clear pattern, but something that shows up just enough to be hard to ignore. And this is a short bonus episode building off of the St. Louis Exorcism case, just focusing on one piece of it. After the St. Louis episode, it's hard not to notice how much of what people expect from possession comes from that case. Not directly, but through what it inspired. Because once something like that gets turned into a movie, it stops being just a case. It becomes the template. So when people talk about possession now, they're usually not starting from a blank slate. They're starting from something they've already seen. And even the word itself, possession, isn't as clear as it sounds. Depending on who you ask, it can mean completely different things. In a religious context, it's usually described as an external force, something entering or taking control of a person. But even within that framework, there are levels. In the Catholic exorcism framework, there are four levels infestation, oppression, obsession, and then finally possession. Sometimes they're simplified to just three levels, which are infestation, which is the activity attached to a place or object, like a house, oppression, which is an external attack on a person, often described as physical or environmental harassment. Then finally, possession, the most serious category where a demon is believed to take temporary control of a person's body. The one that often gets left out in casual conversation is obsession, which refers to an intense attack on the mind or thoughts. Different traditions define it differently. Outside of that, you have psychological explanations, like dissociation, trauma responses, and identity fragmentation. Things that can look from the outside like something has taken over, even if there's no agreement on what that something is. So right away, you're not dealing with one definition. You're dealing with a word that gets used to describe a range of experiences, some of which overlap and some of which don't. If you look at documented cases, whether you believe them or not, they tend to have a few things in common. And most of them aren't dramatic in the way that people expect. A lot of it is behavioral. Behavior like changes in personality, sudden hostility, withdrawal, fixation on certain ideas. Then on the other hand, sometimes it's physical. Things people claim they can't explain, like strength that doesn't make sense for the person, or reactions to certain objects or phrases. But even those reports are inconsistent. And that's part of the problem. Because once you move away from one specific case, you don't get a clean pattern. You get overlap, you get similarities, but you also get a lot of variation. And the other part that tends to get lost is what an exorcism actually looks like in practice. Because again, the expectation is shaped by movies. It's dramatic, it's immediate, it's something that happens in one intense moment. But in real accounts, it's actually the opposite. It's slow, it's repetitive, and most of it doesn't look unusual at all from the outside. In many cases, what's described as an exorcism is a process that takes place over days, sometimes weeks, sometimes even longer. It involves prayers, readings, conversations, and observation. The same actions reported again and again. And the people involved aren't reacting to one explosive event. They're watching for patterns, changes in behavior, reactions that don't line up with what they expect. And even then there's hesitation. Because in most traditions, exorcism isn't the first conclusion. It's the last one. Other explanations are supposed to be ruled out first, like psychological, medical, or environmental explanations. So what you end up with isn't a sudden confrontation. It's something that builds slowly over time. And that makes it harder to define. Because there isn't one moment you can point to and say, yep, that's when it started, or, yep, that's when it ended. It's a series of observations and decisions made by people trying to interpret what they're seeing as it unfolds. The St. Louis exorcism didn't just stand on its own, it helped set the expectation for what possession is supposed to look like. And you see the same pattern in other areas. The Betty and Barney Hill alien abduction case shaped what people think an abduction looks like. If you're interested in hearing more about that case, check out episode 21. There is also the Patterson Gimlin film, which did the same thing for Bigfoot. In both cases, you have something that becomes a reference point, something people can picture. And once that picture exists, it doesn't stay contained to that one case. It starts to show up again, not necessarily in the same way, but in ways that feel familiar, which raises a question that comes up over and over again with this kind of thing. Are people describing what they experienced, or are they describing something they already recognize? The St. Louis case stands out because it's one of the few where multiple people were involved and some of them tried to document what was happening as it unfolded. That doesn't make it true, though, but it does make it different. Because later cases exist in a world where people already have a picture in their head of what possession looks like. And that picture didn't come out of nowhere. So now you end up with two possibilities. Either those early cases help define what people think they're seeing, or people started fitting their experiences into a pattern that already existed. And once that happens, it becomes very difficult to tell where the experience ends and where expectation begins. That's the part that makes possession cases so difficult to deal with. Not because they're easy to believe, but because they're not easy to dismiss cleanly either. Because the more you look at them, the less they behave like a single consistent phenomenon, and the more they look like a mix of something real and something shaped by belief. And when you're dealing with something that sits right on that line, you're never really going to get a clean answer. This has been State of the Unknown. The St. Louis exorcism doesn't end with a single answer for what was happening, or with a simple way of defining what possession is supposed to be. It points to a case that helps shape the image people still carry in their heads, and to a pattern that shows up again and again in accounts that came after it. Over time, those cases have been interpreted through religion, psychology, culture, and expectation. And none of those lenses resolves everything cleanly. Whether you see possession as something spiritual, something psychological, something misunderstood, or some combination of all three, the harder question is how much of what people report is experience and how much is recognition.
