Based on my previous research, it was related to the blocking of dopamine receptors. In other words, dopamine can be somewhat closer to our normal state when we are by ourselves or with people we are relatively close to, and it automatically increases when we are with others. How much can you actually improve this through suggestion? We need real medical support. I'm not sure how accurate my perspective is. Also, English is not my native language, so I apologize for any errors in my writing.
