Anrachán
Anrachán is a term that appears in ancient Irish literature, often associated with a spectral or ghostly presence. The word itself is believed to derive from Old Irish, though its precise etymology is debated among scholars. In various texts, anrachán is described as a fleeting, often mournful, spirit that haunts specific locations or individuals. It is not typically depicted as a malevolent entity but rather as a manifestation of sorrow, unfinished business, or a lingering connection to the mortal world.
The appearances of anrachán are often subtle, characterized by unexplained sounds, chilling drafts, or fleeting glimpses
