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 Scientology: A New Slant on Life.
I was feeling locked in, remembering feeling exited as a child about waking up in the morning, but, as an adult I didn't feel that any longer. The book gave me the understanding why that happened and what I could do to handle it.
