As as student Susan Blackmore had an out-of-body experience that convinced her of the paranormal. However, after years of research, she came to the conclusion that such experiences are a purely brain phenomenon and not evidence of anything supernatural. Her new book ‘Seeing Myself: the new science of out-of-body experiences’ tells her story.

She debates the issues with Graham Nicholls, author of ‘Navigating the Out of Body Experience: Radical New Techniques’. A a researcher in the field, he claims to have had many out of body experiences which were objectively verified through seeing things he could not possibly have known otherwise.
