Had a dream I was transported 5000 years into a confusing and alien future
I got a hotel room and a very unhelpful person who wouldn't grasp simple concepts like "I don't know whether moolins can be converted into ¢ but I only have moolins and all the products seem denominated in ¢ can you help me out here"
I was dream-skewered into a member of the Collective, which was kind of like the Galactic Federation from Rick and Morty. It quickly became clear that I was not from around there, and actually was born around 1 AV in their calendar system.
