In the Harold and the Purple Crayon children's book, Harold walks around at night in his pajamas drawing things with his purple crayon, "and the moon went with him". Towards the end of the story, he starts looking for his bedroom window, to return to his room. He draws a lot of windows, but none of them are the one he is looking for. Then at last he draws the window in front of the moon, so that he is inside looking out at the moon, then he is home. I'd seen this story before, but didn't think about it as a parable until reading it to my daughter yesterday. Then last night I had a nice dream about trying to bridge a gap between people, and experiencing it first from the outside, then from the inside, with a change in perspective like in the story.

Anyway, there's something to think on for an astral projection, lucid dream, or other meditative experience, if it appeals to you.
