Funny Train zaza gun dream

So I was at a fair I think and saw some older teens (collage age I think) shoot someone and my first instinct was to beg to be shot as well (I was 10 in the dream) but for some reason they didn’t but instead took me in and we selled zaza until we arrived at my old neighborhood and I saw a cool rusty Swiss looking train (it looked like some form of European or Russian) and I considered putting zaza inside it (it was moving albeit slowly out of someone’s garage) but then we went somewhere else and I woke up and I’m still trying to figure out the train’s wheels because the rust was rainbow-ey?????
