I am trying to find the name/info about a true ghost story" doc/drama from maybe the 70's or early 80's? It was in color, not Black and white, it was not part of a TV series (I don't think) but was more like a movie based on supposedly true events (kind of like "encounters with the unknown". What I remember is a few segments, one of which was a woman who had some sort of a psychic link with an indian (Native American) mummy. I think the theme was reincarnation and memories of being burned alive?? Another segment was an elderly couple in an RV or trailer who are parked on a salt flat. Suddenly they are hit by many rolling and flying boulders and all hell breaks loose. In one scene they are squinting off in the distance as one of the boulders first approaches. Looking back on that segment, I think it may have been a highly fictionalized telling of the Racetrack Playa "sailing stones".
Sorry, I know I don't have much info.
