“She lives in a large copper castle, surrounded by walls and towers. No one but the king himself can pass in or out, for there has been a prophecy that she will marry a common soldier, and the king cannot bear to think of such a marriage.”
She was lying on the dog’s back asleep, and looked so lovely, that every one who saw her would know she was a real princess.The soldier could not help kissing her, true soldier as he was. Then the dog ran back with the princess; but in the morning, while at breakfast with the king and queen, she told them what a singular dream she had had during the night, of a dog and a soldier, that she had ridden on the dog’s back, and been kissed by the soldier.
This is a part of the fairy tale "The Tinder-Box" written by Hans Christian Andersen in 1835.
In that boldface part, why was "of" used instead of "about"?
I've already read this Q/A; "Dream of" and "dream about". Is there a difference?
But I still don't understand why in this case.
In short, what's the difference between the two sentences below?
- She had a singular dream of a dog and a soldier during the night.
- She had a singular dream about a dog and a soldier during the night.
Thanks for your help in advance.
