Supernaturally is the adverb from supernatural. It describes something happening in a way that nature cannot explain — by gods, spirits, or magic. "The door supernaturally opened" means no wind, no person, no reason we can point to: something outside nature did it. But in real speech, this strict meaning is actually the rarer one. Most of the time people use supernaturally as a strong "amazingly", when something is so far beyond normal that it feels like magic — even though everyone knows it is not. "She is supernaturally calm." "He's supernaturally lucky." Nobody thinks a ghost is involved. It is a way of saying "so much that it is a bit unnatural", with a touch of wonder or unease. The word sounds a little literary. It suits stories, film reviews, and lively writing more than everyday chat, where people just say "weirdly" or "unbelievably".

超自然地；（引申）好得不像真的、簡直神了。日常誇張用法比「鬼神」的原意更常見。
