Boat water slide ride

Date: 10/18/2019

Me and Emily (my sister) where walking around at this festival thing at night and there was this boat water slide (the same thing at movie world) we went up to the tower and we were in the boat and we watched someone go down then randomly we got out, because apparently the boat was broken. Then we were like “oh is there a way out?” So then I found a door and I opened it and there was a person there. It was just a empty room with a talk ceiling and some wires. I don’t remember much after that so I must have woken up. (And this dream happened right after me and my sister had a fight)
