You sound like someone who has never had Tetris vision. It’s mildly frustrating. You close your eyes and your brain starts simulating whatever game you’ve played too much (in my case, dungeon crawl stone soup). But it’s not a fun simulation, it’s more so just a random imagined game state and then predicted next state, vaguely dream like.

Honestly it’s probably the same mechanism as dreaming. Just your brain training itself too hard while you’re still awake.

I've never had it from Tetris or other games, except the "falling sand game". It took a few weeks before it went away. It wasn't fun.

when i was a kid i fell asleep on a pokémon game and for a few hours after waking up lived in a world echoing with one pokémon song. sleep deprivation from staying up all night playing pokémon surely doesn’t help. toying around with the tetris effect is fun. human sensory perception is whack, even without drugs! our brain can play us scenes if we guide it a bit.
