Consider this a vade mecum: an invitation to “walk with me” through more or less uncanny terrains of worlds in the making in search, of(f) course, of monsters. The search will be delving into the areas of “creepypasta:” pieces of cursed prose and pictures that circulate online, waiting to contaminate and possess the next reader. Using a theoretical framework of posthuman and feminist theory, not least the work done by Jacques Derrida and Donna Haraway, this vade mecum asks what it might mean to engage ethically with that which is not supposed to exist, but which haunts us nonetheless. In other words: what does it mean to move, live and engage with spectres in digital times?
