Hmmm... A very technical dream. I'm not an expert, but I love thinking deeply about dreams. My guess is that it sounds like your mind is going through complex emotions? Maybe the plane represented how you feel like you are having to reach a goal by "staying afloat." By autopilot being stuck on, maybe its your mind's way of saying your daily "autopilot" actions that get you through the day are starting to take over somehow. By "autopilot" actions, I mean how people occasionally act in a repetitive or "standard" way to avoid bad feelings in life, such as doing something in the way you think is the correct way to do something, despite how you may actually feel about it. By passengers being there, it may represent how you feel this loss of control in your life is affecting others. The train could be the dangers that are on a path of danger, and your maneuvering with someone else to evade this could represent how your mind may think you need someone's help to get over this problem you feel is coming. Or, it's reminding you that two sides of you are needed to get you through this problem, like your emotions and logic, for example.The elevators getting stuck could represent how sometimes in life you may feel like things are hopeless, but your mind is reminding you how there's still hope as long as you keep trying.
