To dream of God represents an aspect of your personality that's unquestionably or unsympathetically positive. Resisting or failing anything negative no matter the consequences. Dangerous positivity. God might also represent aspects of yourself that are perfect such your integrity, honesty, or compassion for others. The good in you that can never fail and embarrasses other people who may acting negative. Something is being set straight and there may no sympathy whatsoever.
God may represent you or someone else that has the power to do whatever they want. A situation in your life where you can't be repressed or answer to no one. You or someone else that has the final say and can exact consequences if needed.
To be god in a dream may represent your feelings of total power or knowing you can do whatever you want. You may have special talents or superiority over others. Total freedom or feeling more powerful than others.
Example: A woman dreamed of being encouraged by God to jump off a cliff. In waking life she was planning to break free from an abusive relationship and move. God reflected her scary choice to embarrass her boyfriend by leaving him for a newer happier life that was uncertain.
