I recently came across a letter in "New Scientist" dated 11 April 2009 which relates to earlier posts about displaced sense of self.
The letter was from Eric L Altschuler, University Hospital, Newark and Vilayanor Ramachandran, Brain and Perception Laboratory, University of California, San Diago.
"We read your two part series on out-of-body experience with interest (14 March p33 and 21 Mar p36). We were surprised that you did not mention our method, which uses two mirrors to create within seconds the experience of standing outside oneself. (Perception Vol 36 p632.)
This 2007 paper was the first to report a method to perceive being outside of one's body."
