When I was little my sister told me it was a liiittle worm trying to breath..lol she liked scaring me. But it could be several different things, some serious some not. The most common causes are stress, lack of sleep, and strain, more serious causes could be neurological reasons. If it only happens occasionally it's most likely nothin to worry about :)0
