Walking down a dark, narrow corridor, in 12th century London, the walls feel like they are closing in.

The ceiling seems to get closer to you as you grope for the exit. The air is getting thin and you can’t breathe.

This is just one of the ways the technicians at the Haunted Castle of Muskogee is getting ready to play on visitors fears.

Bill Overby, site director, said they try and think of all the little things that terrify people and bring it out in their performances.

“Some people are really claustrophobic,” he said. “We have had them just stop in the middle of the corridor and be unable to take another step.”

The Haunted Castle of Muskogee opened Friday and will run until Nov. 1. More than 42,000 people visited the Muskogee site and owner Jeff Hiller said he expects more.

“The event grows every year,” he said. “We are constantly working and expanding The Castle.”

The newest additions to the family of horrors at The Castle is The Grudge, or lovingly called “Anni,” short for “animatronics.”

“Anni is the coolest thing,” Overby said. “It’s just so big and no one will expect it.”

Nor will they be expecting the Angel of Death flying over their heads either.

“The Angel of Death is huge,” Hiller said. “It stretches about 20 feet across and that’s not including the wing span.”

And of course along with the new stars of The Castle’s exhibits, there will be the favorites as well including Halloween Land for all children under 8 years and tons of vendors and activities in The Village.

“You really need to spend some time walking around and seeing everything,” Hiller said. “It’s a whole night packed with fun for all ages.”
