ELI5: What's going on when you get that tingling feeling in your body after seeing/hearing something you feel is profound?

It's kind of difficult to explain but whenever you hear some very good lyrics in a song or you see a movie trailer that absolutely hooks you this feeling starts.  Almost like a kinda good tingling feeling in your head and body, also my peripheral vision will start to fade when this happens.  What is my body actually doing when this happens?

Some people call it autonomous sensory meridian response (ASMR). No one is really sure why this happens, but it occurs because your senses have encountered some stimuli (visual, auditory, etc). Some psychologists support its existence and say it produces similar effects to meditation, but there is not broad agreeement about why this happens.
