Remember the Future / Dreams of a Foreign Past Realized

Two stories involving time travel. 

Remember the Future: Sonny has it all - if only his wife wasn't perpetually depressed. In using a time-traveling technique called "Remember the Future," he hopes to change his wife's past for the better. It ends up being for the worse (if you think pop music stardom is the worse).

Dreams of a Foreign Past Realized: When elderly Harry dreams that a significant historical event happened quite differently, he awakes to a world where this difference is now fact. Day after day, it's a new event in world history that has changed, and he's the only one who knows about it. Did I mention the Russians are involved?
