"Fever Dream" by Ray BradburyRead about another story on the list.
This is a deliciously creepy story by the master of the uncanny tale, Ray Bradbury. Like all the best short stories, the premise is a simple one: a boy on his sick bed feels that his body is being taken over by more than a mere disease. But he can't make the adults believe that, of course. They think he's making a fuss. And then, suddenly, he feels much better. Don't read this if you are going down with a cold.
