There is a book I'm looking for. I've seen it on a couple years ago, but I lost the name of the title. It's a very specific book, a topic I haven't been able to find much on. It's the authors examination of psychotic experiences that young children often claim to have, i.e. when a child might claim they saw a ghost in their bedroom or have an invisible friend etc. etc. - the author tries to shed light on the fact that children may have actually experienced these sorts of things and it isn't anything to do with a child's 'active imagination'... that they could be highly receptive to their surroundings etc.

Does anybody have an idea as to what book I might be talking about? Any help would be greatly appreciated!
