In general:

The world is the living space in which the human collected his experiences and his everyday activities. A dream of a world beyond the human sphere of influence suggests that dreamer should place its narrow-mindedness of a current situation.

Psychologically:

Dreaming of other worlds and dimensions makes the dreamer’s attention that there are other ways to experience his life more proactively, he should have the courage to try it yet. Maybe he should approach his life with a bit more openness.

Spiritually:

If the dreamer is progressing on the spiritual level, then he realizes that the world belongs to the cosmos. Such a view of the world brings that dreamer must take responsibility for its operation.
