Well folk, have you ever been in the state of thrilled sensation while watching picture being drawn? Yes, I have!
To give you an illustration, watch this movie: http://www.youtube.com/watch?v=CHiKxytbCWk
Recently, I read an article in bbc (http://www.bbc.com/future/story/20130507-does-boredom-give-you-pleasure). The writer gave that thrilled sensation as “tingling around our scalp”. So, the term of this feeling, called “autonomous sensory meridian response” comes from British journalist Rhodri Marsden.
Indeed! This explanation satisfies me after I have went through this feeling for almost my entire life 🙂
