We travel, in this world and in others, in the direction of our interests and desires, and we see what is around us through our personal lens.
This is a practice that can be developed in waking states of altered consciousness, or mukashafa. The Prophet Muhammad scouted out the progress of a caravan en route to Mecca in this way. The Caliph Umar, from afar, scouted an ambush that had been laid for his general Sariya (and sent his general a telepathic warning that was received).
Then there are the dreams in which we seem to join or rejoin another personality, in another body, in a different reality or a very different version of our present world. I have just been reading the travel reports of a prolific dreamer who has found herself entering the perspective, the life experience and seemingly the bodies of different animals, including a small terrier dog and a very large polar bear.
Here's a question to ask when you come back from a dream excursion: who was the dreamer?
