Can playing too much chess make you see everything as chess moves? According to this answer, some schizophrenics who compulsively play chess a whole lot see everything as chess moves. I looked for an alternate source of that information through a Google search and never found one.
Also, I used to play The Legend of Zelda Breath of the Wild a whole lot, maybe many hours a day. After enough time of continuously playing it so often, I felt like I was seeing the real world as part of the Breath of the Wild game. (Of course, playing the game isn't the exact same experience as it would have been if I were out in the Breath of the Wild map in real life.) I had been playing breath of the wild so much and so continuously that when I was exploring the real world, it sort of felt like I was exploring an area that looked like that in the game. After I did as much as I felt like doing in that game, I never got around to playing it again for over a year. I no longer see the real world that way anymore.
Could the experience be something like that for people who play chess so many hours a day?
Quite possible- this would be a special case of the Tetris Effect, as would what you described with your experience with Breath of the Wild.
Anecdotally, someone I knew once played a lot of chess online and experienced similar effects. About 9 hours per day were spent on chess, roughly equally divided between play and study. This person experienced such effects as:
They sent a one-word message and became anxious that they blundered since it was &quot;hanging&quot;
Noticing two socks were on the floor and immediately thinking &quot;good, they're connected&quot;
They also dreamed about chess, which is almost universal among players that play a lot of chess.
I wouldn't expect this happening to you - 9 hours is a lot, and anecdotally, I've spent a lot of time on chess myself and have yet to see any such effects beyond just dreaming about it. They also mentioned that they had tetris effect tendencies.
