Were they playing the S10 version of Over the Horizon through the loudspeakers
No.
The memorial it's was this ~50 roman stone facade with pictures of him and family, and a few art pieces dedicated to him. One in particular that I remember was him in a chair in the style of that old adult swim show about the mormon kid. I checked it out for a while and some old lady behind me was talking to someone about how tragic it was.
Then I left and found my way to someone's driveway down the road who had basically been using his garage as a visitor center. I lied down on some box or something there with a blanket and just people-watched and relaxed, then I heard someone yell "gun!"
I looked up and saw this girl walking towards a girl in front of me with a pistol held out, but he expression seemed kind of playful so I hesitated.
As I got up to leave, the girl with a gun started yelling something to the other girl and then shot her.
As I was running for the garage, about 3/4ths of the way there, she started shooting again and I felt two hit my back. One right by my spine, the other into my left ribs, almost in the side.
It didn't really hurt, so I figured maybe they just grazed me. I yelled "I'm hit" as everyone else was freaking out, and I fell. Then, I could feel blood pouring out of the second wound and yelled that I was bleeding. I was too afraid to actually touch the wound to confirm I was bleeding for some reason, but then I realized I should take my blanket and use it to put pressure on it. As I did that, I woke up in the dark which scared the shit out of me because I thought my vision had just gone black.
Pretty cool dream all in all
