In my dream this morning there was a talented artist; he could draw anything. But when he erased what he had drawn, he also erased that which he drew - person, place, thing - it was gone.
It reminds me of the spell used by the wizard in Tanya Huff's Smoke and Shadows. She would doodle while explaining something until the person to whom she was speaking was satisfied. Afterwards, she would erase the doodle and the memory of the explanation. One limitation of the spell was that the person had to be satisfied that they had received a complete explanation. One drawback was that if the lines of the doodle were filled in again, then the memory would be restored.
This leads me to wonder ...
First, I should mention, the artist in question could not create anything by drawing a non-existant thing. That said, I wonder, if the drawing erased were to be restored ... would the item that he drew also be restored? Could he do it himself or could another do it without his input? Would it matter how well or poorly the image was restored.
I would imagine, however, that IF such a spell reversal were possible, the image would have to be drawn in the same place on the same sheet of paper. But I suspect the reversal is not possible.
I don't remember anything else about the dream or how this man fit in.
