@Tenacity I mentioned once that to control the environment of your dreams you could complete a repetitive task in which your brain categorises the environment as the same, like playing a game all day or drawing in your room, it seems there's a word for this called the tetris effect:
"People who have spent a long time at some repetitive activity before sleep, in particular one that is new to them, may find that it dominates their imagery as they grow
drowsy, a tendency dubbed the
Tetris effect. This effect has even been observed in
amnesiacs who otherwise have no
memory of the original activity.
[14] When the activity involves moving objects, as in the video game
Tetris, the corresponding hypnagogic images tend to be perceived as moving. The
Tetris effect is not confined to visual imagery, but can manifest in other modalities. For example,
Robert Stickgold recounts having experienced the touch of rocks while falling asleep after mountain climbing.
[6] This can also occur to people who have travelled on a small boat in rough seas, or have been swimming through waves, shortly before going to bed, and they feel the waves as they drift to sleep, or people who have spent the day skiing who continue to "feel snow" under their feet. People who have spent considerable time jumping on a trampoline will find that they can feel the up-and-down motion before they go to sleep. Many
chess players report[
