I just watched a BBC documentary, Horizon: The Secret You, about recent results in the scientific study of consciousness. There were three experiments discussed in the program which seemed to me to be particularly key. The first experiment was carried out at the Karolinska Institute in Sweden. It involves having the subject wear a stereoscopic VR helmet attached to two video cameras. Using this simple apparatus, the subject can be given an out-of-body experience, without drugs or meditation.
