Dystopian Korean Movie - Tumblr Posts

I had a dream where it was one of those dystopian Korean films like parasite or squid game and it was about this Society of people where if you want to travel anywhere you have to take this underground elevator that takes you to different levels Underground and once you get to a level you have to pull this Stone tablet attached to a string that takes you to a different level underground and you have to keep doing this until by chance you pull the one that takes you above ground back to the surface world. So you're trapped in this underground elevator until you're lucky enough to pull the right stone tablet. And it's very rare but if you're really lucky and you pull a certain Stone tablet it'll take you to a higher level above the surface level that is for a higher Rich class of people and you get to eat fancy rich people food. Because of the system of travel you are separated from the people you're with and it will be very rare that you see them again.
