Dreaming of travelling up or moving in an upwards direction is a sign that things are on the ‘up’ for you.
This dream can also represent you letting go of repressed feelings and emotions and finally becoming free. Imagine a balloon that has been freed and is starting to float gently upwards, this is the release of your pent up emotions and you will start to see the bigger picture now that you have dealt with them.
Moving up could also be a more literal moving up in the world. You may be achieving your goals, getting a promotion or improving your status in another way. The dream is a positive reminder to yourself to continue what you are doing and you will be rewarded.
