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 Dianetics: The Modern Science of Mental Health.
The book explains how people said to be "normal" can have more than 200 aberrations before birth which contain pain and unconsciousness. A baby is born and before he can start to speak, he can feel terror emotions or excitations caused by the aberration from before birth. This I have verified for myself.
