The sensations were strange. Jon couldn't see, hear, smell, or taste anything. But he could feel. And it scared him to death that that was the only thing he could do.
What had happened to him? He made a wish (a very simple wish) to be dressed and ready to go for school and then suddenly he was like this. There was no darkness or light, since he had no sense of sight. There was no noise or silence, since he had no sense of sound. And nothing was pungent nor stale. It was so hard to explain.
But he had his thoughts. He was still alive, as far as he could guess. It's just that he couldn't move. By himself, that was. Shortly after he made his wish, he felt pressure against himself, in different parts of his body (at least he hoped it was his body - it felt different). And after a minute or so, the pressure was gone, replaced by more of a stretching sensation.
Jon really wished he knew what was happening to him.
