Humans are hardwired to do what we see, hence the term, monkey see, monkey do. The relationship between “catching” a yawn and social behavior is that we subconsciously “catch” the yawn to be seen as “normal” because it is what someone around us has done. A lot of it goes back to psychology. I would suggest looking up Solomon Asch’s human conformity experiment to get a better understanding. :)

This stoker's novel shows how fragile human existence was, and weakened the beliefs of free will and immortal soul. Stoker relied on medical sciences as a physiology and used much of the novel in his characters, brain actions that cast doubt on such beliefs as trance and somnambulism, dramatizing a very common fear at the time of the novel, the Victorian era. It was well portrayed the fear that at that time humans were soulless animals and followed only their physiological and cerebral instincts. The soul and the mind were in conflict. It was the religious faith of the time against the effects considered "paranormal", portrayed in the novel.
