This Edition has much more content and lots of it is way more interesting. It puts flesh on what clinical litmus tests use to see more detail. It has others' testimonies as well. I have had a great many severe, schizophrenic experiences over 20 years. It's interesting because I'm very smart which goes along well with it, I remember them well when you are supposed to remember them, and it's like having more than two brains because you've got your consciousness, your made up one, and the union of the two. This book marks a compact description of such experiences that I believe any audience can enjoy. A teenager will be just fine. Some symptoms to wet your appetite: hallucinations some huge some long, thought broadcasting, dictation of what I was doing, own lexicon, people reading my mind, predictions, God complex, interesting creative detail, long and short memory problems, and many unique ways to see the world!
