To perform an inquisition in a dream is to interrogate oneself.
An inquisition indicates an intense desire for answers in your life.
Dreams of an inquisition represent that you are feeling on the defensive, working out your feelings of heresy, betrayal, going against the system, guilt and shame.
If you are the one leading the inquisition, you are grappling with your own inner critic, judge, and jury, sentencing your inner rebel to pay the price for going against your own moral code. See Heretic and Judge.
To dream of an inquisition, bespeaks for you an endless round of trouble and great disappointment.
If you are brought before an inquisition on a charge of wilfulness, you will be unable to defend yourself from malicious slander.
