I really likes this one it could almost be an episode of the twilight zone :) It seems your grandmothers generation had a knack for telling scary stories, probably because they did not have television yet. My mother used to tell me how her Nanny used to tell her and her siblings horror stories at night and my own grandmother was into that stuff as well. She would watch horror movies to that how I was forever scarred at 5 watching the wax museum LOL!
