We typically watch American Horror Story under our covers with all the lights in our house flicked on. That’s why it was a relief when we talked to Chrissy Metz, who’s making her debut on this season’s Freak Show Wednesday night.

She’s just as scared as we are.

We caught up with Metz on her recurring role as Barbara, aka Ima Wiggles, what it’s like being a plus-size actress in Hollywood and her real-life American horror story.

Now that you’re in the cast, does AHS still freak you out?
When I watch the show, I can’t watch it on my own I was so petrified, I couldn’t sleep [when I watched it alone].

How did you tap into this role?
I really feel connected to this character because I’m very confident and outgoing – I’m like a social butterfly – but I’m human. We all have insecurities … Regardless of your weight, your race and where you grew up, we’re all contending with something.

Anything creepy happen while filming in New Orleans?
There definitely was some kind of energy or something in my hotel room … There’s just a different kind of energy out there. I think New Orleans just has an interesting energy. (Editor’s note: She has since changed rooms.)

Is it awkward being the newbie?
I felt like, “OMG, I’m the new kid on campus. OMG, nobody’s going to like me!” Everybody has been so nice that I’m like, “Oh, okay.” It was a surprise to me. Sarah [Paulson] is one of the funniest people I’ve ever met, always joking and kidding around – and then right back into character.

What can you tell us about what’s next?
Let’s just say that things are about to go down! Stuff is about to happen that people really, truly are not expecting – the cast wasn’t even expecting lots of the surprises.
