Made-up cards have also known to have appeared. I remember this one called, "The Sleeping Rose," which showed a girl with dark hair, resting in a coffin and holding a bright-red rose.
Made-up cards pop up a lot in my dreams, too! They usually feel like odd trumps, like still part of the tarot system instead of oracle cards...
I remember one that was vaguely like The Sun in meaning, but I knew it wasn't The Sun from the image.
Another one was like an oil-on-canvas image of a woman in an orange burqa sitting in the sunbeams by a window, while a gray body lay in the shadows at her feet. The card was huge and heavily lacquered, and I tried to meditate on it because I wasn't familiar with the meaning.
It wasn't so much the card as the situation, though. In the latter dream, I was doing a reading for our housemaid, and I think I'm supposed to help her with something.
But I don't put more emphasis in cards I've dreamed, than most other dream imagery (guessing it was just natural that if I use tarot cards when awake, then my intuition will add the act of reading to its syntax.) The meaning of the dream's usually been clearer, though, if I ponder over the dream-cards instead of trying to figure the archetype of the green penguin who turns into Chevy Chase...
