American Horror Story: Hotel will be unlike any season they've done before.

According to the cast, Hotel will focus on more internal fears rather than the ghosts, witches and Nazi doctors that have terrorized characters in the past. "I think it's about, 'What is the nightmare in your head?'" Denis O'Hare says. "It's not what's externally terrifying. 'What are you hiding from in yourself?' I think that's a pretty strong theme in this one."

But don't think that just because AHS is going a little pensive means it will be any less horrifying. "This one has scared me the most," Cheyenne Jackson admits.
