Dream About Cages And Hallucinations

Everyday for lunch me and my brother goes to the meatball restaurant, bcs he likes it. We always accidentally met my aunty there, and one day her children too in which are my cousins. We ate together there just like normal. One day, suddenly im in a school festival. Its like the usual festival, im with my circle of friends and we hanging out there. We watched a movie, and after that theres this 2 cage that actually just a makin a hallucination vision. So 1 person can actually seems like being inside both of this cages, her left body side on the left cage and the same way for her right. I think shes my friend (idk if shes rlly my friend or its just me i dont rlly remember). When i see it from outside the cage, it makes a hallucination vision that her half and half got cut. One side she has white side and the other black side, i mean her outfit. But when i look closely its changed to her real outfit bcs i broke the hallucination vision. And then move on i hanging out with friends again. And i get an idea for a joke, bcs i remembered abt the cage there. The joke is, guess what this cage kinda like can do? But my friends having too much fun with each other that i got ignored, so i raise my voice repeating the joke but turns out the class infront of me heard it all and being the who answered it for me. The answer they said is the right answer, "what that cage can do is humantraffiking". I walks in the class, say hi to everyone ik there then left. When its time to go bcs the festival ended, i got approached by a teacher....after this i forgot the rest of it
