Researchers to study if out-of-body experiences are real

A group of British, U.S. and Canadian researchers will study whether out-of-body experiences are real, as some people have claimed after surviving cardiac arrest.

In a study run by the University of Southampton's Human Consciousness Project, researchers will examine 1,500 survivors of heart attacks over three years at 25 hospitals in Europe, the U.S. and Canada to determine if the phenomenon of seeing a light at the end of the tunnel or floating above as reported by some is genuine.

To test patients, doctors will place random photographs on shelves higher than the beds in emergency and intensive care rooms, which will only be visible if the heart-attack victims are looking down, the researchers say.

The photos will be confidential and changed routinely, they say.
