Julianne Hough looks like she’s dancing with the devil.

The “Dancing with the Stars” personality stunned fans when she was videotaped receiving an energy treatment that looked like an exorcism at the World Economic Forum in Davos, Switzerland, on Wednesday.

Hough, 31, began to contort and scream uncontrollably as Dr. John Amaral demonstrated the treatment.

“There’s always a huge dissipation of energy and the feeling of relief, release, freedom,” the doctor said in a video posted to Instagram as Hough twitched and yelped. “Expression of emotion may happen when the system moves.”

He continued, “When energy was stored and bound up in the muscles, it gets to dissipate, and if we’re really free to express and allow energy that’s been bound in our bodies to move through — this woman is like, an incredible dancer, actress, just, human being, and she has practiced just allowing things to move through.”

The doctor said most people wouldn’t scream like Hough in that situation, but instead would feel pain.

“What they would have is physical pain, tension in their bodies,” he said. “We’ve just made it easier for that energy to be liberated.”

Several Instagram users noted their concern after watching the alarming treatment.

“Upon viewing this video for the 45 time it is in fact a demon coming out of her butthole,” comedian Heather McMahan wrote.

“WHAT THE. THIS IS NOT REAL,” hair colorist Justin Anderson commented.

“What in the actual…,” Stassi Schroeder added.

Dr. Amaral appears in Gwyneth Paltrow’s Netflix series “The Goop Lab.”
