Dreams about death what does this mean?

im seeking for help in sleep interpreting. So i recently had a dream where i just saw a death certificate and nothing else. I looked at it and saw my grandmother's name who is still alive in real life. I tried to see the cause of death but i couldnt read it. It tho was there i just couldnt read it. I was shocked and half awake and started crying. At that point i think i was awake. So like two days after that i see a dream where i first am an agents and im with this other agent behind a wall on a mattress. We start shooting a guy but at sometime the agent i thought was my friend is shooting me. The next place i am at is a chruch. there is a job to take dead body parts in plasic bags to a trash. I take the job and start doing it and a boy follows me. I had a few friends with me when i was taking the bags. So when we are done and leaving we r walking on this brigde and i go "that boy was so dumb" and i talk shit abt him. Hes right behind me and starts a fight. I yell at him like can we talk and i wake up just when he is about to punch me. So what can all this mean to see two death related dreams in 3 nights? Thank you already!
