Dream About School Shooting And Dance Party Glasses

My last dream was about how we lived right under the school in the office and there was a meeting or just school and my mom was sitting with this boy I hang out with and I said “where would we go if there was a shooting” and they just laughed and then all of a sudden we see people running and saying shooting and my mom and the boy just sat there unphazed and I just watched then they got everyone into the cafeteria and my whole family was there. My dad, mom, both my sisters and this random girl who was apparently my grandma. Then the person who was there before started saying that he wrote down to kill so that’s what he needed to do next. So out of each the tables we were at they picked 1 or 2 people and I think it was to live or maybe die. They picked my moms mom even though it wasn’t her mom. And my sister and just skipped over me because I wasn’t pretty enough. Then my dad found like a weird gun. And this girl came up to me and gave me these glasses that make everything seem like a dance party and brighter and said that I needed to go to the arrow down there. Then I said what she said that I needed to go over the river and started singing “down around the river benn” and then my mom came and woke me up
