Disclaimer: This theory is the result of personal experience with schizophrenia by the author and not necessarily applicable to every individuals with schizophrenia.
Our five senses are connected to our feelings, of course.
The five senses, or feelings, is in touch with the reality, such as daily activities.
However, the thinking of the schizophrenic is disconnected from the feelings.
Moreover, since the sufferer lives in his own thinking, it is like he is constantly in dreaming state. Overly focus on thinking or dream resulting in positive symptoms, something that normal persons do not have, and at the same time, disconnecting from reality or five senses resulting in negative symptoms, something that normal persons would have with motivation and interest in daily activities.
Why then the thinking escapes from the feeling? I guess it is because the uneasy feelings, such as the bullying.
It is then considered the body’s defense mechanism to disconnect the thinking from the feeling, to reduce the painful experience.
