The Tetris Experiment

Playing Tetris can influence your thoughts and dreams, particularly during the transition from wakefulness to sleep. An informal experiment involved participants playing Tetris in the mornings and just before bedtime to investigate if it would affect their dreams. While one participant did not experience Tetris dreams, they reported that thoughts of Tetris still surfaced in their mind as they fell asleep. This reflects the Tetris Effect, where engaging with a game or task significantly shapes one's thinking and visualizations during hypnagogia, the transition phase between wakefulness and sleep.
