Dream About School Shooting 72

So I had a dream. The dream was about a school shooting and I think one of my friends was in it I think this girl was 9 years old and I was 19. I was in this elementary / Middle School outside hallway where everybody was. The girl told me that's going to kill somebody with a gun that day and she told me to get ready for it right? So I went to the wall for the tiniest of cubbies, and I got my phone and put it in my pocket, and the next thing I knew was this little girl shot the boy in the chest and then at everybody else, she didn't tell me she was going to do that. I start running away from people and away from The scene. I was running beside everyone but I took a route none of them took. I went through doors to distract the shooter just in case they were coming after me. Then I met up with everyone else and met an old friend, Ava. We got to the corner of the school as the teacher was talking about the situation. I saw this little grassy passageway a few of the kids ran to do I grabbed Ava's hand and left the group, running into the forest. We ran for a while when we stumbled across this open lake area with the bluest of skies and greenest of grass. I saw three people there, Billie Eilish and two of her friends. I was so shocked and even noticed that she finally was in my dream! I was so excited and told my friend Ava that it was her, she doubted me, but I doubled down and went up to her. I went up and said "oh my God! Billie eilish?!~" and Billie looked surprised and she was on the phone so she was precccupied. She stepped back and her friends stepped forward and told me that she was busy and not in the mood right now. I said "oh..." In a somber tone and then my dream ended.
