Dream About Horror Movie Scenario In Box Shaped Room

It was almost like a horror movie. It was me and a bunch of other people in a box shaped room. It wasn’t to big but kinda decent. It was really rusty and there was like a garage door on of the walls with a cage that was like down %75. There was a like a 2x2 box cage next to the garage door, in the middle was like a floor separating the top and bottom and in the top left box was a man who was in the box, it was like he was the game master, sorta like Jigsaw. The first part I remember I was in the corner and he was yelling and I climbed to the top of the cage and he said there were mines in the ground and that we didn’t know where they were. He was trying to souly kill us. He detonated the first one and it was where I was standing in the corner and someone ended up getting blown up to pieces. The whole thing was moving so fast, bomb, after bomb. He laughed the whole time happily with excitement. People kept blowing up left and right until I was the last one left. Next I remember jumping down, then he came out the cage. He set a propane tank on fire, the room was so hot. He had on this juggernaut outfit. I quickly climbed back on the cage jumped down and kicked him and he fell on the floor and repeated when he got back up. The propane tank exploded while I was on top of the cage, killing him. I jumped for what I thought was still a propane tank about to explode I quickly hid in the bottom left cage with a metal door, half of it ripped off. I heard the tank rolling and it kept bumping against the cage. It sounded like it was coming closer and closer, when it got in my view. I seen that it wasn’t a propane tank but something small, I couldn’t really make out what it was. I crawl out the cage go up to the garage door. On the bottom of the floor I picked a tiny key and a pocket knife, i don’t know why I thought I just might need it. At the bottom was this small metal latch that open the gate. I entered this second part, a small room most likely a second entrance. There was a motorcycle, I got to the last gate door and lifted this yellow handle. My heart pounding, racing for me to get out, mixed with this feeling of excitement. I open the gate to this alleyway and then I wake up from my dream.
