Halloween comes early with “Haunting Sarah” (8 p.m., Lifetime), which stars Kim Raver (“24”) in a dual role as Erica and Heather Rose, 36-year-old identical twins. The sisters are very close, but their respective offspring, both 6 years old, are even more attached. Early on, Heather (or is it Erica?) observes, “They’re more like twins than we ever were.” You know nothing good can come of that.

When Heather’s son David is killed in a car accident on the way to school, the family is devastated. But Erica’s daughter Sarah remains eerily calm. She has no reason to mourn or grieve, because David, or rather the spirit of David, is talking to her all the time.

At first, Erica sees this as a phase, but when Sarah begins to predict traffic accidents and other dreadful events, Erica retreats to the family’s summer compound to take Sarah away from grim memories. But while on vacation, Sarah and Heather become ever closer, shutting Erica out of their lives. Is one twin trying to use her sister’s daughter to bring back the spirit of her dead son?

If this sounds creepy and slightly confusing, you’re right on both counts. Despite some cliches, “Sarah” is an above-average TV shocker, a bewitching blend of “The Patty Duke Show” and “The Exorcist” with a little “Rosemary’s Baby” on the side.
