There was a man being executed. It was such a horror to watch brutality of execution by mystic absolute power/authority figure, like a god, the voice asking his guilt and killing him mercilessly with gigantic iron mace and other metallic weapons. I was watching that and knowing it's my turn very soon. And I listen my guilt from the voice of god. I was accused of something like not doing what I supposed to do and just letting my life going as killing the time.

God

To dream that God speaks to you, signifies feelings of guilt, eternal punishment, and damnation.

Execution

To see an execution in your dream, suggests that there is something or someone you need to cut out from your life.

To dream of your own execution, indicates that you are harboring some strong guilt. Perhaps there is a bad habit or aspect of yourself that you want to rid yourself of.

Mace
To see or use mace in your dream, represents your quest for objectivity over subjectivity. You do not let your emotions rule your actions.
