premise: I fell asleep and took a nap , and I had a dream we were trying to hide in Costco overnight . There was a mix of my school and church friends there . First we tried to hide behind these mattresses , but the security guards would shine lights on us and yell at us , and we would just scatter to a new hiding spot . I finally decided on climbing their huge metal shelves . What do I like about Costco ?
hypothesis: jungle gym like structure
