Scientists discovered that they can use virtual reality technology to trigger an out-of-body experience (OBE), or more specifically getting a person to watch a video of themselves with their heartbeat projected onto it. This new discovery "could lead to new treatments for people with perceptual disorders such as anorexia and could also help dieters too." Continue reading for a video and more information.
Participants saw their own heartbeats visually imposed on their virtual doubles in the form of a flashing outline around the body that pulsed in sync.
After a couple of minutes, many of the participants reported sensations of being in an entirely different part of the room rather than their physical body and feeling that their "selves" were closer to their virtual doubles.
