When people are in sync, like at a rave or during marching, they can feel a strong connection to others. It's like being part of a bigger group instead of just being alone.
This feeling of unity happens because everyone is moving together and focusing on the same thing, which can even change how we see ourselves. We start to feel like we're all one entity.
Experiences like raves and military marching may help flip a 'hive switch' in our brains, making us more likely to care for others and feel less self-centered.
