Weird space thing

Date: 11/8/2023

This dream happened a while ago but basically my school decided to take us to outer space and we went to mars but it wasnt mars it was a house that didnt have any walls or a ceiling and the teachers told us that if we fell off the house we would fall forever because there was still gravity for some reason. So one by one people starting falling off the mars house thing by accident and eventually I was the only one left and me and the teachers that were left got back on the rocket and flew back to earth
