“Mom and I had talked years back. We’d watch these paranormal shows, and I’d say, ‘You gotta show up for me.’ And she was like, ‘I’ll show up as one of those orb things.’ ”

Easterling has had similar encounters. Two months ago he visited Peru with his wife’s ashes to hold a private ceremony at the spot where they said “I do,” commemorating what would have been their 15th wedding anniversary. “I took a picture, and this blue orb is right between my eyes,” he says, showing off the image on his phone. “It’s been a supernatural year.”

Even as Newton-John’s condition declined, her positive spirit endured. “She loved her spot outside her bedroom to watch the birds,” says Lattanzi, who moved back in to help care for her mom. After she’d spent some time in the hospital near the end, “we were like, ‘She doesn’t want to be here,’ ” says Lattanzi, and they brought Newton-John back home.
