Shortly thereafter, she said, she was confronted by her uncle David Miscavige, who she said told her, "What you did is unacceptable. You're not gonna get any more special treatment," she recalled. "I was like, if special treatment means being held down and not being allowed to talk to your family, then I am happy to be rid of it."
Celebrity Center International is a Scientology Church located in Hollywood, Calif. It is aptly named, as many Hollywood celebrities are members of the Church. Cruise and his wife, Katie Holmes, of course, as well as John Travolta and wife Kelly Preston, and Kirstie Alley.
"I had one auditing session in Scientology, and I never did drugs again or had the urge to do drugs again," she told ABC News in a 1998 interview.
Auditing is a fundamental and common practice in Scientology. It's a kind of counseling session in which a person is asked a series of questions and negative feelings and thoughts are identified -- and hopefully purged -- through the use of what's called an e-meter.
"You just basically hold the two cans, and I think they measure electrical resistance," Lawrence Woodcraft said of his auditing sessions. "They have a whole list of questions: Are you withholding anything, do you have an upset over anything. In other words they want to find out what's going on in your life."
Said Jenna Miscavige Hill: "Once a week we would get a meter check where they just have you sit there, and they'd ... observe your needle, and if it's like dirty, then that means that you're hiding something."
Hill said the e-meter and auditing sessions could also be used to interrogate, asking things like: "Do you have any intentions to leave and never come back? Do you talk about bad things about the church to your parents?"
In 2000, Hill's parents were preparing to leave the Church and Hill said that around this time, her e-meter sessions suddenly intensified.
"I just got plucked out of my usual activities by a very high representative of the Church and was interrogated on the e-meter," she said.
Hill also said there were times when she was physically restrained during auditing sessions, "to a point where I was yelling and screaming."
But according to a Scientology report from May 2006, provided to "Nightline" by Hill, the Church said she was the violent one. The report states she had a "long history" of "verbally and physically accosting other staff members … neglecting duties … damaging church property … mayhem … mutiny … enturbulation."
Hill doesn't deny the incidents, but said Church restrictions pushed her to the breaking point.
"I'd been very unhappy while I was there," said Astra Woodcraft, who was becoming disillusioned with the church.
"They came up with a new rule, 'OK, that's it. No more kids,'" she said.
Her father said, "She was very upset when she was about 16 or 17 and told me they suddenly decided to change the rules and Sea Org members were no longer allowed to have children."
Hill said that "if you get pregnant when you're in the Sea Org you either have to leave, or you get an abortion."
Said Astra Woodcraft: "I remember thinking wait a minute, I never agreed to this. I am 17 years old, I haven't made a decision that I'm not going to have children."
Two years after the policy was established, Astra Woodcraft learned she and her husband were expecting a baby.
