In the Western world mental illness is completely misunderstood.
When you deal with psychosis or schizophrenia for example, you are actually experiencing higher states of consciousness. The problem is that the ego is messing up things because it is not used to it and can't handle this different state of being, it literally goes through hell and creates all kinds of stories about what is happening so that's the reason why one gets mad.
