Is Praying To Imaginary Gods Mental Illness?

Mental illness is the notion of a dysfunction within the workings of the brain, the problem is, that to define whether some sort of a nuerophenomena is a normative function or a abnormal dysfunction - a psychologist or a psychiatrist will sit with a patient and listen to him describe his weird experiences, and from his interpretation, he may write down that you have schizophrenic episode or a dissociative disorder.

Personally, I rather look at mental illness as the idea of different mindset, between neighbors, nations, continents, cultures, thus Praying to imagined gods is nothing wrong, first of all because it's not dangerous by itself, and second - if you live in a circle society in which people believe in gods, you're not mentally ill, you're educated.
