Did PLL's Sasha really get buried alive?

In the shocking Season 4 finale of Pretty Little Liars, we learned that Alison DiLaurentis was buried alive by her own mother. Sasha Pieterse (who plays Ali) reveals that filming the scene was just as creepy! "It was four in the morning, and they dug a 6-foot hole and started burying me alive," she shares. "It was realistic and freezing. I had sap dripping down my arm and fake lightning in my face." It's safe to say that's one PLL memory she'll never forget! "Being buried alive is the craziest thing I've done up to date," Sasha says.
