Published in 1909, Ambrose Bierce's "The Death of Halpin Frayser" is a masterwork of psychological horror that blurs the boundaries between dream and reality. The story follows a man who falls asleep in a California forest and experiences a nightmarish vision involving an uncanny encounter with his dead mother. Bierce constructs a layered narrative that interweaves Frayser's backstory—his obsessive relationship with his mother and his mysterious disappearance in the West—with the investigation of his corpse, leaving readers uncertain about what is supernatural and what is madness.
