I had a dream that my partner abandoned me in the airport…
Dream interpreters believe an airport is about your life needing change- whether that is change in your relationship, work, with family or friends. It could be something you need to change in yourself.
It might be that you have a desire to travel more, so the airport has a more literal meaning or you may need to move into another phase of your life.
If your partner leaving you made you feel emotional or upset and you were scared to be left alone, this can also be a sign that you need a fresh start in some area of your life.
Another interpretation is when someone close to you abandons you in dream; it could mean trouble in your future. It's however something you can overcome because you've had a warning sign from your subconscious.
As you were the one who was left behind it's often an indicator that whatever troubles or problems you come to face, they will be resolved quickly.
