Main article: Death Omens
Banshees cannot only predict death, they can identify where death occured, and sense someone's death becoming aware of their passing away just by 'feeling' it.
During Season 2, Lydia would experience fugue states, after her powers were activated, though she didn't understand why they were happening. One fugue state occured in Omega and she was confirmed to be present to sites linked to death: the Hale House, where the Hale Pack was killed and Beacon Hills Cemetery. She would also be drawn to dead bodies, murder scenes, and receive visions or noises indicating how, where or when someone would die.
In 4x03 - Muted, Lydia was drawn to the Walcotts' family house, not only because of the family being murdered, but because the Walcotts were wendigos and fed on rationed dead bodies. Just like at the Glen Capri she makes out the same human faces upon the wood of the family's secret panel leading to their 'game' locker.
