If the plane crashes into the sea in a dream, it is an auspicious dream. It is a sign that the dreamer, whose eyes are very high, will come to the places he aims, even if he has great difficulties in the jobs he will enter, will be very successful and will be a man who is pointed out by everyone.
To dream that you are sleeping on an airplane journey means that there will be a change in your life without being aware of it. If you have seen yourself waking up just as the plane was about to land in your dream, it means that you will encounter a surprising change.
