We (?) were at a grocery store when we heard the sound of planes overhead. everyone at the store suddenly stopped where they were and just gave eachother looks of worry. i looked up toward the cieling and saw the sound of the planes led to it cracking and releasing a bit of debris, but it was still not collapsing. The rumbling got louder until i huddled on the ground and heard a huge explosion. i saw a flash of light and was dead. I was a student at a large university, but I was a bit of a loser and this was apparently known to everybody on campus. This university was at the forefront of climate change research. The architecture was large-scale and fatalist, but mixed with certain organic additions. The school's president issued a warning that we all needed to make our way to the underground shelter immediately and bring with us any food or water we could find. .... I was running along with my classmates down this ~20ft wide spiral staircase. although the steps were normally sized, the overall structure was very large. my classmates were all taller than me. As we ran, we heard announcements through the loudspeakers telling us to bring water. I entered the shelter (i was one of the last to enter) through a square opeining and was greeted by a straight set of stairs leading downwards into the dark. On the left, there were tables built into the walls as far down as i could see and each sat 2 students looking downwards. each of them had a plate in front of them of brussels sprouts (?) and carrots diced. most of them were obese. the table closest to the opeining was free, but i didnt know if i was allowed to take that seat as it may hve been reserved. I was told by the girls seated below it that the seats were not taken. The school's president was giving a speech about how this meal of brussels sprouts and carrots was all that survived from the cafeteria, and we would not have any more food to eat. I went to sit down and I got the feeling that I would have a revelation. .... I was on a roller coaster. it was going through a tunnel and other roller coasters were coming onto the track from different directions but did not crash.
