In psychosis, the mind disposes of or deflects certain (real) information. Is that so different from a “nonpsychotic” mind?

Unconscious mental activities (nonpsychotic): A mental process that is usually in keeping with, or at least remains cognizant of, socially understood reality.
Unconscious mental activities (psychotic): The mind disposes of or deflects certain (real) information-which may have external and/or internal sources-from integration.
Reality versus delusion (nonpsychotic): The mind that travels to alternate realities or dream states is also able to reintegrate with reality (eg, waking up from a dream).
Reality versus delusion (psychotic): Reintegration with reality (eg, waking up from a dream) does not readily occur, and at its worst, psychosis "takes over the mind."
