When I feel creatively stuck, I love to zone out.
Just lie down in bed or on the couch and just drift away. It is delightful to do, and it is great for your brain.
You can use clouds for that, letting your thoughts drift away with them. You can also meditate to zone out, knit or listen to some relaxing music.
No matter what you do, the goal is lying down, a calm smile on your face, your eyes either on a fixed point in the distance or close.
Wanna zone out with me?
