I dreamt I had made a nuclear bomb. It was about the size and shape of a pocketwatch, and it was detonated by clockwork. I made it back in high school, and I was visiting the high school and decided to pull it out to show to people. But evidently the clockwork had grown touchy over the years, and it kept starting to count down and I had to stop it. So, my high school physics teacher took me to a stream, where we threw it in. It started gouting flame out of the water, so we swam downstream ahead of the flames and by the time the stream had joined a large body of water, the flames had stopped.
I also had stranger dreams, about flight and swing dancing and magic and inimical machines, but they’re too fuzzy to recount here.
