I dreamed last night that I was almost shot

I was sitting on the couch with my crush and this man walked in and he was old with a white beard. I buried my face in the couch and he shot everyone else in the room and walked away. I ran, I was in this underground house (confusing but bear with me) and he came back and chased me. I was going to different locations and this white haired man was gunning me down. It was like I was switching into different dreams and he was following me? Anybody got an interpretation of this?
