Treading the path gently

I'm still reading Lone Frank's book, Mindfield: the penultimate chapter is about that almost uniquely human ability – lying. Why we lie, how we lie, how we justify the need to lie, and whether there's any foolproof way of catching someone lying, are all questions that neuroscientists are currently trying to answer. It occurs to me that dreams have such an important place in our culture because we generally believe that they are a window into our unconscious mind, a place where we cannot tell a lie, even to ourselves.
