i once had this dream (non-lucid) where a guy with a nuclear bomb strapped on his body stood there, just stood there...
so me, my classmates and some teacher (who is also my neighbour, and WAS my teacher in real life) must escape in a video game-like seting with a timer on top of the "screen"...
we always escaped the blue purple explosion: we did it! and we did it again! and again! for 3 times
