Wowza. That's an intense nightmare. When I was a kid, I had this one recurring nightmare. It always started with this intense sense of urgency. The task I had was always slightly different, but it always gave me the sense that if I failed, the world would die. Every single time I had this dream, I failed in the task and I knew it. Right before the dream would end, I'd walk outside, sit down on a picnic bench and watch birds flying through the sky. Then a bright flash would happen in the distance and I'd wake up drenched in sweat. I didn't understand it as a kid, but now I realize it must have been a nuclear explosion. I fail at disarming a bomb. Fortunately I'm a welder, so there's not much chance I'll end up being responsible for nuclear holocaust lol.
