In this episode we explore the history and origins of Halloween, its rituals and customs such as carving pumpkins, trick-or-treating & fancy dress. We examine how it developed from a pagan event (Samhain) with Celtic spiritual tradition to the multi-billion dollar commercial juggernaut it represents today. We examine the psychology of fear behind Halloween and why so many people enjoy being frightened. Also, what are the reasons for people to act so out of character on Halloween. We delve into the deeper and often darker concepts behind the mask. How does it lead the loss of the self? We analyze the true image of our persona with its multiple identities by uncovering the blurred boundaries between life and death. Finally we consider the most disturbing aspects of the mask, a process called deindividuation. By donning masks & costumes, are we staring into an abyss of deviancy? What lies beneath a mask, a more sinister persona? Or a first step to stripping society of it’s individuality.
