Poltergeist 2: The Other Side (1986)

Synopsis
One of the more effectively spooky and financially successful horror films of the '80s got an inevitable sequel with this effects-heavy installment. The Freeling family is trying to grapple with the devastation wrought by the ghosts and ghouls that destroyed their lives. The insurance company doesn't believe their story about what happened to their house, so Steve (Craig T. Nelson), Diane (JoBeth Williams), and their kids, Carol Anne (Heather O'Rourke) and Robbie (Oliver Robins), have been reduced to living in the home of Diane's mother, Jess (Geraldine Fitzgerald). Unfortunately for the Freelings, however, their new residence, just like their last, is situated on a haunted patch of unholy ground. A century before, the mad cult leader Kane (Julian Beck) slaughtered his followers nearby, and his evil spirit has returned in an effort to kidnap Carol Anne. When the Freelings realize what's happening, they call upon the psychic medium Tangina Barrons (Zelda Rubinstein) to help them again, and they also receive aid from a kindly Native American spiritualist, Taylor (Will Sampson). Noticeably absent from the sequel was older daughter Dana, who had been played by actress Dominique Dunne; Dunne was killed in 1982 by her obsessed boyfriend. ~ Karl Williams, All Movie Guide
