Jon woke the next morning to the pain of something sharp digging in his back. Reaching round to pull if out, he was very surprised to realise it was a thistle and more surprised still to find himself stark naked in Sarah's body lying in the middle of a field.
"What the hell!?" he exclaimed. Something odd was going on here. He remembered the dream he'd been having and sort of recognised the meadow he now found himself in from it. But where he actually was he had no idea.
There was no one around, fortunately. Jon knew that naked young girls could get themselves into all sorts of bother if they wandered around the countryside.
Jon had no idea where he was but he didn't plan on staying long, he had a history test to get to. He looked around for the rock on the ground. After several minutes of searching, his head close to the ground digging in the thick grass, and still no sign of it he was beginning to get a little worried.
"Looking for this?" a deep male voice suddenly said from behind him. Jon stood up and spun round to be faced with a man with a huge white beard, wearing what looked like the standard attire of a farmer. The man looked Jon over appreciatively and Jon suddenly thought to try and cover himself up. Sadly, he did a rather poor job of it - he really needed three hands.
"Um. Yes. Can I have it back please?"
"Now that all depends, doesn't it missy?" he grinned unnervingly.
"Please, sir, you haven't exactly caught me at my best here." Jon complained.
"Oh, I dunno. You look pretty good from where I'm standing, makes me wish I was twenty years younger."
And suddenly he was. And he knew it. He quickly looked at the rock and with a rather shocked look on his face seemed to put two and two together.
"My, my," he said. "This is interesting!"
