A Nightmare on Elm Street 3: Dream Warriors
Kristen is a teenager disturbed by terrible nightmares. Her mother Elaine dismisses it as all in her head, although she does spend money on psychiatrists to help Kristen work past whatever is plaguing her. What is plaguing Kristen is 1428 Elm Street and Freddy Krueger. After a particularly harrowing nightmare, Kristen awakens to find herself still trapped in the dream, where Freddy takes her hands captive with her bathroom faucet and slits her wrists. Kristen's mother enters the bathroom to see Kristen with a razor in her hand and a slit wrist, and she is sent to the Westin Hills psychiatric facility.

Hysterical, Kristen refuses to be sedated, but soon finds solace in fellow survivor Nancy Thompson, who is now an intern at the facility. The other teenagers within the hospital walls are also experiencing nightmares of Freddy Krueger, and are systematically being slaughtered. Kristen and the others learn from Nancy that their parents burned Freddy alive, and that he is exacting his revenge on the children.

Kristen has the power of flexibility and gymnastics in her dreams. She can also pull people in and out of dreams, as Nancy learns. After a particularly nasty outburst after the firing of Dr. Neil Gordon and Nancy Thompson, Kristen is sent to the Quiet Room and sedated. Nancy and the others go into the dream to make sure she's not left alone with Freddy.

Kristen and the Dream Warriors defeat Freddy, but not before losing people in the process, including Nancy, which devastates Kristen. The end of the movie shows her and Dr. Gordon at Nancy's funeral.

Trivia
A Nightmare on Elm Street 3 was Patricia Arquette's first movie.

According to Rachel Talalay, who worked on every Elm Street film but 5, Patricia Arquette was not offered a chance to reprise her role as Kristen for Elm Street 4. According to imdb, it wouldn't have made much difference as Patricia Arquette was pregnant at the time anyway 

Actress Tuesday Knight, who played Kristen in Elm Street 4, also sang the opening song of the film.
