Powerful dream - the feeling I get is one of stormy change, confusion (re: the change - how is your relationship changing? will it change?), fear of change...all the blood and killing of the 'zombie's, with the Authorities permission....hmmmm, makes me think that there are unconscious issues that you are trying not to see...and maybe justifying this by feeling that you have permission from your Saturnian self (the part that limits and restricts)....I don't know, I could be waaay off base, but if it was simply about the transformation of your relationship I don't think it would be soooo violent, upsetting and fearful...
What happens when you really write this dream down in super detail, writing down each bit with how you felt....?
