The Fear of a Cruise Ship Exploding and Sinking

I dreamed I was in class. Outside the classroom window was an endless sea. I saw an incredibly beautiful cruise ship passing by and called everyone over to look. The cruise ship was tiny in the distance, shining brightly in the sun, and the sea was sparkling. As soon as the classroom window was opened, the sea breeze blew in. It was perfectly beautiful. Then we saw that beautiful cruise ship suddenly speed up and leave, so we went back to class. Next, our class also organized a vacation on a cruise ship. It was an ordinary cruise ship, but still very nice. Even though our living quarters weren't even as big as our school dorms, everyone was very happy. Then we encountered that incredibly beautiful cruise ship again. For some reason, it was very close to us, spinning rapidly in place. The people on that ship were terrified, but the cruise ship showed no sign of slowing down. Then, that beautiful cruise ship suddenly exploded. After the explosion, it began to slowly sink, but for some unknown reason, our cruise ship also began to uncontrollably speed up and circle the exploding ship. This even caused the secondary and tertiary explosions of the sinking ship to almost catch us in the blast. But in the end, we made it away from there. No one escaped. No one made it out of that exploded cruise ship. Everyone's mood grew very heavy. Our ship stopped for some unknown reason and had to remain stalled on the sea for the night. I was deeply uneasy, so I didn't stay obediently in my room; I kept trying to find official staff, like stewards or something. Midway, the cruise ship even lost power for a few minutes and took on water once. Finally, I found a few stewardesses. I asked them: is the ship really going to explode. They just awkwardly told me not to make such dangerous jokes, but I could see they were still a bit scared. Yet they didn't know the answer either, and then I truly fell into despair. I already felt like I was just waiting to die on the ship, and now, after running around for so long, I had only deepened this suspicion—neither confirming it nor dispelling it. I felt so helpless. I thought of the cruise ship that had already exploded. On that ship, some people were there to work, some were there to vacation, and some had spent their entire life's savings just to see the sea once. But they all died. They might have died helplessly, they might have died painfully, or they might have been as desperate as I was, or perhaps even more desperate. Then I returned to my room, looked at the water that had already risen to my heels, climbed back into bed, ignored the voices of my classmates, and went to sleep. Then I woke up.
