As shuttle flights and space stations become a part of our modern vocabulary, space travel becomes more accessible.
Consequently, dreams of it also are more common. This sort of dream is often simple wish-fulfillment-a desire to see the world from a different perspective. However, it can also be a dream of escape, travel or search. The purpose of the travel is obviously the key to resolving the dream. Another potential scenario for meaning concerns the mode of travel. Are you in a spaceship, or in something more familiar (like your car)?
Dreaming of space travel is a very exploratory opportunity. It can also mean that you are lost or are groping for something in a vast vacuum.
Did you want to be in outer space in your dream or did you simply find yourself there? Did you feel safe being there?
