Obstacle Course

Playing an obstacle course game in my dream with a bunch of people and I remember carrying my bottle of water with me and losing it at some point. There was hay all over so I assumed maybe it fell into that. Kept doing the course when I bump into my uncle Dave who was also doing the obstacle course and I mention losing my bottle and he says he uses it as a marker to remember someone or something he saw or something like that. I had dropped it while going from one obstacle to the other and he saw it and used it as a way to remember something he needed to do after the game. Anyways after that I think I had a lil romance with CS.
