But with her dress removed, Anderson, who admitted she was in the room willingly, said things took a turn for the worse.
"When I became really uncomfortable is when he put his hands around my neck," she said.
Anderson said Sheen became incensed when she begged for him to release her.
"He started throwing things. He threw a lamp. That was the first thing he picked up," Anderson said, her voice cracking. "And he threw it across the room at me."
"When he started throwing things at me I became shocked, scared," Anderson said.
Charlie Sheen's lawyer Yale Galanter responded to Anderson's allegations Sunday night in a statement to ABC News.
"Ms. Capri never made any allegation of wrongful conduct on the part of Mr. Sheen the night of the incident. She has posted on her website that she was 'fine' after the incident but if you wanted to see more of her enter the web site for money," Galanter said. "We will defend this lawsuit vigorously and will never pay her a dime. These allegations against Mr. Sheen are completely false, and are a blatant attempt to cash in on his celebrity."
Anderson's lawyer, Keith Davidson, told "Good Morning America" that he could not confirm or deny that he or anyone from Anderson's team had been in contact with Sheen's camp about a possible settlement.
A civil suit against sheen is also expected to be filed today in Los Angeles Superior Court.
Anderson told "Nightline" that she feared for her life.
"He was, from the beginning of the night, very loud and he had no hesitations when it came to using derogatory language or cuss words," she said to Ashleigh Banfield in the "Nightline" interview, adding that "towards the latter half of the night, it got really bad. He started yelling racial slurs."
"He threw the lamp against the wall in my direction … And once the lamp flew, it was like there was just stuff coming from every angle. He was just -- anything he could pick up, he was trashing the place," she said.
Photos obtained by TMZ show a rumpled bed and strewn chairs. One of the chair legs appears to be broken.
When police officers arrived at the famed luxury hotel, they found Anderson locked in the bathroom of Sheen's suite. Police said the room had been trashed. Sheen was taken by ambulance to a nearby hospital for a psychiatric evaluation.
"He was calling me a whore a lot. And he was yelling things like, you F-ing bitch. If you don't come out here, I'm going to kill you. If I get in there, you're going to be sorry. If I get in there, you ... whore, you whore, whore. Like he just keep screaming and slamming on the door," she said.
Anderson also tells "Nightline" that she did not know Sheen's children were on the same floor in the hotel.
"How did you feel when you saw that?" asked Banfield.
"Kind of like same feelings, like is this guy a joke, is he kidding me?" Anderson said. "And, you know, just I entertain the thought, you know, but knew ultimately it wasn't the right decision."
Anderson told "Good Morning America" she was never paid the $3,500 she was promised for attending the dinner with Sheen.
