Why is it that after a few days of square dancing then your brain is full of square dancing?

1, because square dancing is a relatively dynamic and rhythmic activity, when you dance for a few days in a row, your brain may have adapted to the rhythm and movement, thus forming a conditioned reflex in the brain.

2. Square dancing activities are usually social in nature, and dancing with other dancers can enhance your social connection and emotional experience, which may also become a deep part of your memory.

3. Being full of square dancing may also be related to your personal interests, habits and way of thinking.
