Dreaming the Perpetual Dream

What if you dreamed someone else's life?
Link has always made it a point to keep things simple, but now his cubicle life has become so stale that he would rather spend it sleeping. His doctor gives him a prescription meant to keep him sharp and focused throughout the workday. When the weekend rolls around, boredom leads to Link falling asleep right after taking a pill...and that's when the fun starts.
In his dreams, Link is transported across the universe to a colony of spaceships in search of a new home. He meets an AI who informs him that half of the fleet is in danger of extinction. And the man whose body he occupies in his dreams? He's the one orchestrating their demise.
Now Link must make a decision; does his waking life deserve some real attention, or should he try to save the space convoy from destruction? By the time he makes up his mind, it may be too late to do anything about either situation.
