Dimensional Drift (Original)

[Written by Nature from @natureprincess48]

What if, every time you fell asleep, your soul was moved through dimensions to another person's body? What if you lived in two different worlds that you pass through by sleeping? If your body with your soul in it dies, it's game over in both worlds. If you don't sleep, you're never going home.

What if you fell asleep in one world and never woke up in the other?
