During manic, or especially Mixed-Manic phases...the mixed manias are when psychosis is scary. I will get paranoia, and begin to form delusional beliefs that my mind holds on to and runs wild with, until heavy meds eventually bring me back down. I am not psychotic during every mania, but it's usually present during the most severe episodes I've experienced. I cannot recall psychosis when I am in a Depressive Episode, where it's not Mixed.
