The Oneironaut's Odyssey

My dreams usually hard to recall the second night after going to sleep late, it was still a cool dream from what I can remember.

Dream
I recall being in a warehouse building, it was quite big and there was some emergency going on. I get the impression that we (me and whatever faction I was with) were on the defense. At some point I remember grabbing an automatic rifle from a weapon rack. There was a large space rocket in the building, we hopped inside and launched it. I remember the power of the engine propelling us up, it was really intense. The building was collapsing all around us as we shot up, the ship then tilted and started navigating around the falling debris. We just managed to duck out of the building and into the open sky, and then had to pull straight up to avoid a tall wall or something. Because we were going up at too extreme of an angle, the ships engine sputtered and stop, at this point the spaceship is now a helicopter instead. The helicopter blades stop spinning and the it starts to free fall. There's massive panic, we're trying desperately to start the engine, but it's a damn helicopter, even if we do will it stop the fall?!?! Right before we hit the ground the blades spin into action, instantly the helicopter slows and then shoots off forward in a very non-helicopter-like fashion.
