Admittedly, we were psyched to hear Rachel review sinister encounters with glossolalia (aka speaking in tongues) and unexplainable levitation. Little did we know, the scariest stuff is devoid of human possession.

"Spaces, believe it or not, for the most part over my last 12 years, have been the [cases] that are the scariest," Rachel continued.

"When an entity holds a space, it's more malevolent because it's such a challenge to hold a big space. ... Like, I've had situations where sinks have been pulled from walls. I've had situations where half the roof comes down on a brand new or renovated space."

Rachel recounted a disturbing first-of-its-kind exorcism that put her in physical danger.

"The one in particular that was my most challenging, is the only time that an entity has actually been able to touch me and hurt me. And I still carry a scar from that," she said.

Rachel signed an NDA when she was hired, so she was unable to tell us where this exorcism happened. All she could say was that it's "a space that a lot of people go through, a high-traffic area."

"I walked in, and I was like, 'This feels different.' ... There were a lot of deceased people that were really weird. And it just wasn't normal. When you're dealing with an entity that holds space, they usually hold a bunch of deceased people. It's a mass trauma space," she continued. "And they're usually so grateful for you to be like, 'Okay, let me help you get out of here. Let's release this.' These people were like, 'We're not going anywhere.' It was like The Shining."

Contrary to popular belief, a dead person cannot attach to a living person.

"Deceased people can be very annoying and [they] do not shut up. Once they know you can hear them, they want to talk all the time. Not the same as entity. Entity is insidious and doesn't want you to know it's there," Rachel detailed. "The longer you don't know, the better they feed."

Regarding the anonymous space exorcism, things came to a head when the vengeful entity grabbed Rachel's hand.

"I was very alarmed. Listen, as far as the space went, it is not in the space anymore. Like it's out. So technically, it was a success."
