Dream About Building Fort Abandoned Place

I was at an abandoned huge place and me and my friend were building a fort with items in the abandoned place then we saw a group of like 20 kids our age doing the same thing but they were using stuff from outside and not inside so we just did the Samee thing and then there was a slide and I was sliding down it with my two feet like I was surfing and then music started playing and everyone closed there eyes and a person said everyone go to sleep and then people were peeking for fun saying “I’m peeking” but I closed my eyes because I thought something bad was gonna happen and then Somone got an allergy or something and then the hospital came and that was it !!
