I personally feel that both dreams mean the same thing. The tornadoes and the gang. Both are large forces. Both are not in your control. Both are threatening to you. Both can cause bodily harm to you and others around you.
I feel that this si a pattern of dreaming that is addressing issues of feeling that things in your life are out of your control. There is danger. There is a feeling of being a vicitim of something. You sense trouble headed your way. Trouble that you feel helpless to control. Maybe you feel small and unable to meet the demands of a situation you are dealing with. But i honestly feel that this is only 2 versions of the same message.
Good luck.
