Pretty much the worst thing that can happen in a horror movie is if it says it's based on true events.

Well, these people claim they saw ghosts in real life, and what's creepier - caught them on camera.

1. The woman who went to a medieval witch prison and got possessed.

A group of paranormal researchers went to Essex, England to investigate a place called 'The Cage' where women accused of practicing witchcraft used to be imprisoned back in 1582.

Upon reaching there, they decided to perform a seance to contact the women who'd died there.

While another team watched the proceedings from another room.

But nothing could've prepared them for what they were about to see.

Right in front of their eyes, a participant's face appeared to have started changing.

The team watched in horror as Debbie's face apparently twisted in a devilish grin and then went back to being normal.

The incident freaked the team out so much that Debbie was immediately called back.

And then just stands on the edge of the crib while letting out a blood curdling scream.

Seriously, you need to listen to it to believe how horrific it sounds.

He seems to be opening opens his arms as if waiting for someone to pick him up.

And all this while, he maintains perfect balance on the crib.

But then suddenly, he seems to get pushed back into the crib by an invisible force.

5. The haunted office with ghosts as bosses.

While the location of the video isn't clear, some say it's in Manchester.

Anyway, that's not important. What's important is the fact that as much as we want to believe it's fake, it does look kinda real.

The chairs look like they're moving on their own.

And drawers seem to be opening on their own.

Now we don't know whether this is real or just another example of really good editing, but it sure is shocking to watch.
