Your brain receives a lot of data every second and discards most of them, this is mostly unconscious and instinctive (we had a post about your brain instantly recognizing your name even in noisy rooms a few hours ago), however, you can make an effort to process infos you’d normally ignore. It’s more evident with other senses, for example you could feel your heart beating if you focus, even in less sensitive areas of your body (not only hands, face etc)
