Well put about the conscious and subconscious, Flux. And what a fantastic experience! I know what you mean by wishing you could photograph it.

I'd be ever so interested in whatever you found regarding the symbols you were able to jot down.

I experience similar, waking up to seeing symbols. A couple of weeks ago I woke to see an enormous symbol of the Eye of Ra. And it is curious that I somehow often know the names of the symbols (such as "Eye of Ra" ), as if the symbol/s is accompanied by instruction or some translation. One morning I woke to the Eye of Osiris and I knew it was distinctly meant NOT to be the Eye of Horus. And I thought to myself...fair enough, but I didn't [consciously] know about the eye of either!

I will say, regarding my own experience, that in the case of the Eye of Ra, as I woke an entity that I know as "the mother" was speaking to me, giving me instruction on my spiritual quest, and this symbol appeared above her.
