Not to wax religious, but could this be from the Ghost of Boyd Packer Past, checking for Little Factory activity?

Reads like a visitation dream, which are often considered to be "real" due to the hyper-awareness experienced during them. While you may have had an actual supernatural experience it is also possible that it was a natural experience.

This may not have any real similarity or relationship with what Nomomo related, but for some reason it reminded me of a couple things I experienced or heard about.

The first was a roommate I had in college, who could carry on a perfectly rational conversation with me while he was obviously sound asleep. He knew he was asleep, and would correctly answer yes if asked if he was sleeping. He would lie there with his eyes fully closed, all relaxed in deep slumber, would be able to carry on a perfectly normal conversation with anyone in the room. The next morning, he wouldn't remember a thing about the conversation or anything else that transpired while he was asleep.

The second was a conversation I had with the friend of another roommate of mine who had come to visit. He told us about an experience he had while a U.S. Marine, stationed in Germany. He was on a nighttime training maneuver with his platoon, hiking through the woods. He was so dog tired that he fell asleep while still hiking, with his eyes wide open. He was walking straight towards a tree and was about to collide with it, in a zombie or robot like state, and was unable to slow his pace or change his direction, until he stubbed his boot on a protruding root, which caused him to wake up just enough to be able to steer around the tree, instead of colliding with it.
