I have had a lot of experiences with seeing people doing things in detail. Also with the blue world. You're right Meg, that you don't need to figure it out. Sometimes it is even accompanied by the feeling that "something important is about to happen" or "what I'm seeing is the answer to all my questions."
I've decided that none of this is of any importance. Now I just watch, then go on with my life as if it was any normal occurance. I believe that what we are seeing is clairvoyance, and sometimes it is in another place, sometimes in another time, sometimes a previous life. Sometimes it is even the future, and I believe sometimes it is another planet or dimension, because I've seen furniture that wouldn't fit any bodies we know on earth.
I believe the strange feelings that come with it are just the result of using a "sense" that we don't normally use, so part of our brain attaches false importance to it. You know, like a guy raises someone from the dead, so people worship him.
So my solution is to ignore it all under the assumption that we're like babies developing clairvoyance and clairaudience and don't understand it yet. I do watch them with fascination, however because of the "high definition".
