Dream Of Harrowing Nightmare

Today was such an awful nightmare that I ended up waking up from it around 8:55am, which I never wake up this early duing weekends, so I know something was wrong. My dream revolved around the political topic as well as I think was human slavery, well, the modernized version of it. I ended up being stuck on this little island thing and watched as more people that were brutally beat were dumped on the floor like trash. As I started to walk closer, one of the people in charge walked up to me and told me I was next. My dream shifted, and next thing you know I was in my dad's bedroom, and it looked like nighttime. I had a gun, and I was looking at him while crying. I told him I had to shoot him to live, and he looked at me and just smiled. I told him to find photos of his childhood, and he kept swiping until I told him to stop. He stopped on a photo of his step dad, and smiled when saying he was glad at least someone took care of him. At this point I was crying even harder, and my grip on the gun was shaking, until finally I pulled the trigger. I wasn't looking at him, I ended up looking away. And I never got to see his dead body. I could hear more voices entering our home as I cried louder, until they took me away too. Heres when the dream again shifted to a giant white building, where we started upstairs, and they told us that we would have to run until we get killed. Starting off strong, I had a good gap inbetween my captors, and decided to start heading all the way to the tippy top, when I tall obese man stopped me with wide eyes and told me that he'd love to slaughter me on his bed and cut me up. My dog suddenly spawned out of no where and I told him to attack- and he did! He was biting their leg like crazy, and I ended up getting away. But the guy said that if he were to find me or my dog, he would personally hang us and cut us open. We then continued to run, until most of us ended up in the same area, since some had already died. There was a lady underneath us (we were standing on glass) as she yelled at us all the "good" things that were gonna happen like gay's would be killed and that god would finally rule the world (which I didn't understand since I will say I am an athiest) and I could make my own connection that I don't appreciate it when people try to push their religion on others. But continuing, we started to run off as the lady screamed louder and louder at us to stop and she continued to scream that she'd catch any of us that were gay and she'd put a bullet in our heads. We climed to to the top, where they announced that even if someone's finger peaked from the top, they'd shoot us. Someone ended up falling off. Lastly, they told us that we had to carry an instrument back, and whoever had the instrument they were thinking of, they'd cut them up. Each instrument was of various sizes, and I believe I had a keyboard. They ended up picking a girl with a flute, and they ended up slaughtering all of us in a soundproof room, where my dream ended when they touched me. After I woke up, I was experiencing an unsettling feeling and I couldn't breathe properly and my perception of time was off.
