Hypnotic delusion

Ever heard of Cotard's delusion – the belief that you are dead, or Capgras delusion – that your loved one is an imposter?  These persistent beliefs can have serious consequences. In some fascinating work, researchers at Macquarie University are now using hypnosis to recreate some delusions in healthy volunteers in the lab, to help understand and treat them more effectively.  And Lynne Malcolm finds out if she’s hypnotisable.
