Dreaming of being chased or chased by aliens, you are out of breath. This kind of dream reminds people of the real life that is always full of pressure, so the source of pressure is an important key to this dream.
But more often, chasing your "enemy" is often your own incarnation, and you can't get rid of it at all. This embodiment is actually your instinct, such as moral sense, sense of responsibility, sense of guilt and so on. If the "enemy" is a part of yourself, then the end of the chase is very important.
You may have found a safe hiding place, which means that you can get inner peace by temporarily escaping. But this is often a manifestation of self-deception, adding disguise to oneself and deliberately not feeling anxiety. This dreamer is generally weak in character.
