Welcome to Jungian Psychology and the wonderful world of enantidromia. As humans are General Intelligences, we're capable of entertaining contradictory courses of action/thinking at the same time. At some point our conscious faculties "meet" our unconscious faculties, and the period of time when the two start to integrate into a whole individual is a bit of a wild ride that practically no modern practitioner of psychology I've met seems to even be aware of anymore, and can absolutely go awry.
