A tall ship and a star to steer her by (starwreck) wrote in valarnet,
I'd say they were living the same life. And this isn't the first time. One of my earlier dreams, there was a transporter accident and I swapped places into a sort of mirror universe, one where humanity had conquered the galaxy and most of us were evil bastards.
This time I started dreaming from the perspective of this alternate me. The big timeline change was my father dying the day I was born, and then later the ship responsible for his death destroying one of the founding planets of the Federation.
This me was a lot more rash and impulsive, a bit like how I was in the waking world before I started dreaming the first time. Much younger, too, when he was forced to take command.
