@Kamo vibrations are emotional energy, what you feel. People give off all sorts of vibes. In my experience some radiate positive energy and open everyone around them while negative energy tends to create the opposite effect. I feel it's more important to always be looking inward, or at least have some attention to your body even while interacting with others. This will help with anxiety and keep you from being consumed by others' egos.
We often get caught up in our own stories, taking life so serious. The mind gets filled with thoughts which lead to emotions being triggered. Having an awareness of these thoughts (what causes these vibrations) and the belief systems behind them can help disassociate with the mind made self. This in turn ends suffering and helps create peace and love.
