Seriously, every time I tell people about my dreams they say i'm on drugs.... One time I had a dream that Ronald Regan's son murdered my mom and foreign exchange student. Then he went after me and shot my hand. Right as he was about to shoot me in the face, I woke up. What do you think that means?
You think you have crazy dreams? I go in and out of galaxies and realities in my dreams. I meet entities named Anecdotal Myers next to my bed. I get abducted by aliens and the day after I have a hardcore euphoric sickness.... I have dreams so real that I think I'll never be able to leave this new dream reality... and that was when I wasn't on drugs.
Murder is the death of an idea or a change in your views, reagan killed an idea or changed your life possibly in a way symbolic of whatever the foreigner represents(a stereotype). The shot in the hand is a disability imposed on you and forcing you to change your way of life both in work and in social grouping. its a rough outline but might help you understand what it means
