In a plane with my parents, about to take off. My mom says something ominous, and I know it's going to crash. My dad says I can get out the front if I hurry, but we turn a corner on the runway, and now it's too late. We're facing a big hill sloping down, like in SF. There are buildings all around and to the front. We start to take off, but we're not getting enough height, and the belly of the plane starts bouncing off of stuff.
