It took way too long, but I finally remember one of my dreams! I was at a triathlon event with rowing and fencing instead of swimming and bicycling at some kind of campground-looking place (maybe a melding of my memories of a nearby campground irl and a camp I attended up north?), and someone (I think it was my mom?) was egging me to participate. I did, and I was off, running down the track. I don't recall seeing any competitors around me, though. When I finished my first loop of the track (because it was shaped like one of those high school running tracks, but on dirt), I quit, coming off of the track. My mom asked why I stopped, and I told her that I wasn't fit enough to finish, but I would try again next year. I'm sure there was more after that, but it's all missing. Still, it's something.
