Being arrested in a dream is rarely connected to any real legal concern — instead, it typically reflects a broader fear that consequences for something are about to catch up with you, whether or not you've actually done anything wrong.
Being arrested for something you didn't do
This common version often reflects a fear of being blamed or held responsible unfairly — worth checking if there's a current situation where you feel you might take the fall for something outside your control.
Being arrested for something you did do
Can reflect genuine, if low-grade, guilt about a real decision or action — the dream processing accountability you haven't fully faced consciously.
Being unable to explain yourself to police
A frustrating variation, this often points to a fear that you won't be given a fair chance to explain your side of a situation — worth examining whether that fear matches a real current dynamic.
