eventually, every "must be supernatural" phenomenon will have a rational, explainable, physical cause

The research provides a physical explanation for phenomena usually ascribed to other-worldly influences, said Peter Brugger, a neurologist at University Hospital in Zurich, Switzerland. After severe and sudden injuries, people often report the sensation of floating over their body, looking down, hearing what is said, and then, just as suddenly, find themselves back inside their body. Out-of-body experiences have also been reported to occur during sleep paralysis, the exertion of extreme sports and intense meditation practices.

The new research is a first step in figuring out exactly how the brain creates this sensation, he said.
