Flying: sense of being on route to your desires, need for a vacation or getting away.
Landing: coming back to reality from that desired, grounding your self, the changing situation regarding an ideal or desire. Time to put ideas into action.
The true definition is found in identifing the type of plane and your personal feeling of aircraft. If you fear air travel, dreaming of being on a passenger jet in flight is likely to be an expression of fear involved with some sort of travel. However if you LIKE to fly then this could also mean happeness. And it can also indicate a desire to rise above it all, an escape.
To see an airplane in your dream indicates that you will overcome your obstacles and rise above to a new level of prominence and status. You may experience a higher consciousness, newfound freedom and greater awareness. To dream that a plane crashes, on the other hand, suggests that you have set overly high and unrealistic goals for yourself.
If you dream of piloting an airplane, you will achieve something of outstanding merit in the arts or in your business. If a passenger, you will have your income increased. If you fall or bail out of an airplane you may expect several months of hard luck. Traveling by an airplane is a portent of a long period of indecision regarding your love affairs.
