If you want to find out more about Dianetics and Scientology, the best way to do this is to read an L. Ron Hubbard book on the subject. I personally recommend you read Self Analysis.
This book really helped me with my memory and feeling good about the earlier times of my life. It was a very personal experience and helped me find out what kind of shape I was in as a being and how to predict how I would act under certain circumstances. It also helped me realize that life can be improved and led me on the path to that improvement.
