Jacques Derrida coined the neologism to describe narratives of the future. Hauntology is the idea that the present is "haunted" by lost futures, and refers to the return of elements of the past that "haunts" the present as a ghost. So imagined futures, instead of exploring new futures, itself becomes a form which is haunted by the exploration of past ideas of the future. This is the whole idea of retro-futurism that we often see these days.
