I have a theory that sometimes mental illness is manifestation of a naturally evolved attribute gone too far. Sort of a "cancer of thinking" if you will. In this case I would say it is the the ability to perceive and relate patterns. A powerful attribute of our species and one of the defining features of intelligence I believe. But then it gets out of control and the pattern matching starts matching things that don't actually match. Only a wild theory. I have no reference nor training in the subject. Just trying to match patterns:)
