My daughter's dream

My daughter recently had a dream:
She said there were 3 princes and a king. The 3 princes were all stealing each other's shields and squabbling. The king had a shield too and was just shaking his head in frustration of the princes.
Then they each found their own shield and their own key on barrels with their names written on them.
One barrel was in the front of the room off to the side, the other barrel was in the back of the room and third barrel was to the side of the room.
The oldest prince was the first to see the barrels and since he had better eyesight, he decided to go for the barrel that was the most hidden.
The barrel in the back of the room was the youngest princes.
The king had already gotten his barrel and key when he was still a prince.
The 3 princes were trying to hide these from each other but then the oldest thought he should show his shield and key to the king so he did and the other two princes followed and showed the king also.
Once they all showed the king their shields and keys, a door which had been on a wall but had no known way to open up suddenly showed 4 key holes and they each had to put their keys in the holes in the door for it to open.
When it opened, there was a blinding light and then they walked a little and there was a door with 4 shield shapes in it.
They each put their shield in their corresponding shield shape in the door and then it opened up.
She said that then she heard God talking to them from inside that door after it opened up and then she woke up.
She said that she knew from the dream that these were spiritual doors, not physical ones.
