Every night, I dream of something chess-related or just chess! It is a lot to take in, but the concepts are essential for life and what you're going to apply in future games. The length of those dreams is longer than you think they are! It's just an excellent opportunity to sleep on the facts of the game. On my end, it takes up the entire night to dream about and of it. I don't ever get nightmares because "dreaming chess is dreaming life".Â
