My boss started the zombie apocalypse to save her husband, and I was the only one that could stop her
This dream seems to be highlighting your feelings about power dynamics and leadership. Your boss, who likely has authority over you in your waking life, is the one who initiated the zombie apocalypse in the dream. This could suggest a fear of your boss having too much control, or the idea that they could make drastic and dangerous decisions.
The fact that you were able to stop your boss in the dream could signify your desire to take control of your own life and be independent. It may also show that you feel capable of handling challenging situations even when they come from a source of authority.
Overall, this dream may be a reflection of your anxieties around authority and control, but also demonstrates your ability to handle unexpected and potentially dangerous situations.
