Can you think of when you started having each of these kinds of dreams?

If there were my dreams, I'd say the tornado one had to do with loss of control or things "spinning out of control"? Have you felt that way in your life about anything? The gangs are probably more about how you feel around others, as if you're "ganged up on"? I use to dream about spies and/or mafia/hoodlum sorts when I was working hard in therapy. I guess it was my feelings about my therapist and working with her. I was anxious/a worrier.
