The fourth type is from the archetypes of the collective unconscious. These are personality firmware, of the brain's operating system, which when active, can take on an autonomous form, parallelling to the ego personality. Back in the day, the late Psychology Carl Jung could treat such patients with his theory of the collective unconscious; psychosis. This now requires drugs, since the rest of the talk theory is not advanced enough. Drugs numb it out. Knowledge of the collective unconscious gives tools that allow coexistence and/or a way to shut these off.
As an example of this effect, that most people have had, is falling in love or infatuation. Something triggers a driving compulsion that puts your head in a cloud. It can be sort of nice and alive, so most people do not see this as a problem, but a natural part of life. It can become a problem if the other person does not reciprocate, but the firmware will not shut off. One is left floundering and reliving.
There are other firmware that have a more sinister effect and often drive the sociopath. In a sense, it can take the form of an evil spirit that tells the person to do things. These firmware can also project making it appear outside you. It may not be a vision, but a projected gut feeling about something out there, walking in the woods at night.
With oppressive law and the need to repress the evil to avoid punishment, the archetypes can polarize to good and evil; angels and demons. This is why in myths and fairly tales have good and evil characters; polarized by law and knowledge of good and evil. Natural archetypes are more neutral.
The archetypes can become the paradox of the inner voice and the inner self. The inner self is below the archetypes, while the inner voice, depends on how deep you go. It can cone from the inner self or from above the inner self; firmware. The shadow is half way between the ego and inner self and its inner voice is caused by law and repression of the darkness; It follows us around like our shadow. The repression consolidates the shadow, and itcan have a life of its own; Angry Liberalism playing games. I sense possession since many cannot successfully, reason, while lecturing on reason; projection effect.
