Once upon a time in the frozen north, Santa looked out and saw that parents and other responsible adults were taking care of the bulk of his responsibilities. Making sure that all children had toys to unwrap on Christmas morning, by providing gifts for their children and donating to charities to provide a happy Christmas to less fortunate children. Between this and the elves inability to replicate modern name brand toys, the elves were starting to get bored. They had even been starting to play pranks on each other, which was putting them on the naughty list.
Santa could not stand for this, elves in his employ, on the naughty list? It could not be. He needed to take action. Now since the remaining world's children could be taken of by about a third of the elf-force, what was to be done with the other two thirds? He thought and thought, but nothing seemed obvious.
Earlier this past week, Mrs. Clause had spoken with Tammy the Elf. Tammy was a beautiful elf, as far as elves went, and she had described a prank that Jimmy had played on her. Jimmy had waited until she was asleep, then had joined her dream, where he had engaged her in some very explicit sexual activity that Tammy did not wish to share with the big guy's wife. Tammy didn't object to the sexual nature of the dream, but her husband Larry did when he found out that it was deliberate.
Elves are very sexual creatures, which is why they basically live in a commune at the north pole with the Clauses. They do not worry so much about sharing their partners, but to do so without receiving permission first, even in a dream, is very poor manners.
The Clauses knew that they lived with some very kinky elves but up until now did not realize that they had the ability to join and manipulate dreams. They wondered if this was a new skill or if it was something that was something that only worked between elves.
Santa asked Jimmy to come in to his office for a cup of coco and a chat. "Jimmy," the big man began, "I've heard a tale that surprised me today. I heard that you have the ability to join other elves dreams."
