Do you sometimes find that you have knowledge in the dream world that you do not normally have in real life?

Here's an interesting experience that occurred to me last night:

I dreamed that I was at a garage sale in my old neighborhood, and an old lady had set out a table upon which was a large bust of the Egyptian god Anubis, with the head of a jackal. When I awoke, I lay in bed for a few moments remembering details, then turned to the pad I keep by my bed to jot down a few keywords. I wrote "old woman garage sale anubis bust," without really thinking about it.

then on my way to type it into my dream-journal, I realized that I am not at all familiar with the names and appearances of the Egyptian gods, and that I probably had made a mistake in naming the god Anubis in my mind. But when I looked up "Anubis" online, I found that not only was that the correct name for the jackal-headed god, but that many EXACT statues exist like the one in my dream.

Is it unusual to have knowledge like this in the dream world?
