Remote viewing and astral projection are related. From what I've read about remote viewing, it sounds like the lines between looking at a target location and going there start to blur.
Sounds like it was remote view or astral projection to me, or maybe a combo of both. If you read religious texts you will start to see that many of the experiences listed in them are astral projections or something related to them. You have given us a good example. Another one that I can think of is the book of Revelations in the Christain Bible. Read it and I do not see how anyone could say this do not take place on the astral or higher plane.
I remember my dad saying once that: "Muhammad(the prophet) had visions of the camps of the enemy and new always where they were..." Just now Im starting to think that it could have been astral projection, what do you think?(It could have been remote viewing too, thought)
