Literary usage of "taisch" spans a spectrum from the supernatural to metaphorical, lending depth to narratives steeped in folklore and cultural tradition. In some works, it represents a ghostly apparition or vision—qualities underscored by its Gaelic roots as a spectre and a form of second sight ([1], [2], [3]). At times, it fuels ambiguity in character perception, inviting readers to question whether a presence is human or something uncanny ([4], [5]). Moreover, the term is interwoven with cultural belief systems and personal odysseys, reflecting both the persistence of ancient lore and the modern skepticism toward spectral tales ([6], [7], [8], [9], [10]).
