A banshee is a type of creature from Irish folklore that is said to be a spirit or fairy that wails and screams loudly. It is usually believed to be a warning of impending death, often for a family member or someone closely related to the people who hear the banshee's cries.
It is said that the banshee can take on different forms, including that of a young girl, an old woman or even a bird. Some believe that the banshee is a harbinger of death, while others think that it is a benevolent spirit that is trying to help the family by warning them of danger.
Many people also believe that the banshee only appears to families with Irish ancestry, and that it is a sign of the family's connection to their Irish heritage. While belief in the banshee is less common today, it is still an important part of Irish folklore and culture.
