I've had several dreams where I will be outside (normally outside my house) and as I look up, a commercial jet is flying over head very low. I get the feeling it is going to crash and as it passes over, turns and heads straight for my house. I'm never actually ON the planes in these dreams. Any ideas what this means?

Interpretation: It simply speaks of your associated fear of this type of event occuring in your life.  It also displays your grief for others who have had this type of situation occur to them.  Your subconscious is suggesting that this is a fear of yours and that you do not want this to happen.
