Scientists develop technique to induce out-of-body experiences

From The Guardian:

Scientists have induced the age-old phenomenon of out-of-body experiences in healthy volunteers for the first time.

In his experiment participants wore goggles containing a video screen for each eye. Each screen was fed images from a separate camera behind the participant and, because the two images were combined by the brain into a single image, they saw a 3D image of their own back.

Dr Ehrsson then moved a plastic rod towards a location just below the cameras while the participant's real chest was simultaneously touched in the corresponding position. The participants reported feeling that they were located back where the cameras had been placed, watching a body that belonged to someone else.
