Did you know that ghosts in literature and folklore are often depicted wearing clothes, even white sheets? Historians have long been fascinated by this phenomenon, which dates back to the Victorian era.

One explanation is that ghosts are simply dressed in their usual attire because it's the mental picture we have of them. Another theory suggests that ghost-seers dress the ghost through unconscious processes.
