Isolated Island Academy: The Robbery

I dreamt I was going to school on a small island with my friends, and then a female bandit hijacked the entire school. If we didn't listen to her, she would kill us. At first, it was fine; she didn't have that many demands, and we got used to it. But later, people started dying inexplicably, and only then did fear begin to slowly spread and ferment. (Many people died inexplicably, but I only remember two cases.) That time, my friend and I were walking downstairs in the school normally, heading to the field for morning exercises and to listen to the principal's speech. While listening to the principal, I turned around as usual to chat with my friend. But shortly after I turned, I heard a loud bang, followed by the screams of students and teachers. My friend stood there, dumbfounded. So I asked her what happened. She told me: The principal exploded. Me: ? So I pushed through the crowd to the front, and saw the principal all over the floor of the podium. (You know what I mean.) Another time, my friend and I were lining up at the cafeteria for food, and the female bandit walked up beside our line, watching us. Then she suddenly pulled out a gun and aimed it at a male student. The male student suddenly seemed to turn into a monkey, very nimbly grabbing the edge of the window with his hands and swinging out just like that. The female bandit followed closely behind, leaping onto the window, and fired a shot at the 'monkey' in mid-air. And so, that male student turned into a red firework between the two teaching buildings. (The female bandit seemed to be using a shotgun.) People were dying completely at random. Everyone was terrified and uneasy, and we all started keeping our heads down, hoping not to be the next one. Until one time, when we were lining up again, I turned around to chat with my friend as usual. Then the female bandit suddenly started handing out flyers on the side. Although it was baffling, everyone took one anyway—who would want to risk their life? So I reached out to take one too, but right as my hand was about to touch the flyer, I suddenly froze. I don't know why, I just froze. Then I saw the female bandit pull out her gun, and my body suddenly moved out of my control, flying under the eaves to hide, just like a monkey. But while my body was out of control, I suddenly remembered something: the female bandit had never stopped us from leaving the school? Many people had wanted to leave the school before, and the female bandit never stopped them. But we never saw any rescuers, nor did we ever see the people who left again. The school clearly occupied 90% of the island, yet we never heard their voices or saw any traces of their lives. It was as if they vanished into thin air the moment they left the school. Then, as if hearing my thoughts, my body started running outward. Sure enough, the female bandit didn't shoot at me again. The moment I left the school, I regained control of my body, but it was a bit different. I noticed my body was translucent. I was dead; I was now a soul. Then I looked at the female bandit. She made eye contact with me, as if she could look a soul in the eye, and then she signaled with her eyes for me to go behind the school. So I went. There, I saw some people like me. Behind the school was a tree, and there was a lot of fruit on the tree. Someone told me the female bandit said that as long as we ate the fruit, we could leave this island and go to the outside world. So I ate it. Because the fruit was sweet and delicious, I even ate a few extra. Then I headed to the beach, where I saw someone rowing a boat to pick me up. I got on the boat, and shortly after boarding, I wanted to turn around and look at the island, but I woke up before I could turn my head.
