I find it interesting how different games can work their way into your sleep in different ways, too! For the Final Fantasy series and other narrative games, I usually find myself dreaming about the characters. When I got really into the puzzle game Baba Is You, I'd dream about being stuck on levels, and sometimes I'd wake up with the solution to an actual puzzle I'd been struggling with in my head. When I was playing Little Hope or Omori, I had trouble fully sleeping at all; I lay in a half-asleep haze, haunted by the game.
