This question is a little difficult, it is used to describe a female ghostly creature and its appearance will predict someone's death

Mary's telephone?

回复 @啊啊是谁都对：Sorry, no. This ghostly creature comes from Irish folklore

回复 @圆环之理：The Morrigan?

回复 @啊啊是谁都对：I looked up the dictionary and saw this word is indicated to Celtic war goddess. But sorry, still not the right answer. The creature I mean predicts the death by wailing

回复 @圆环之理：bean sídhe？

回复 @啊啊是谁都对：WOW, very good, you're right. I mean indeed Bean Sídhe (Banshee)

回复 @圆环之理：Banshees also appear in the computer game <Ghost Master>. They can scare mortals by wailing

回复 @圆环之理：Thank you very much. I learned a lot of things about Irish folks.
