You were reading a spy novel before sleep. It takes place during the cold war between the USA and the Soviet Union. You were really tired but it was so exciting that you couldn't put it down. You ended up dozzing off with the book in your hands. But it wasn't the end of it. The story goes on in your dream, however, you're the protagonist now. You have to find the key of the reactor and retrieve it to the headquarter. You managed to pass through the guards outside, but they send in patrols every 10 minutes, so you have to be quick. Good luck!
