The phrase encompasses concepts for disguises designed to evoke fear, unease, or dread, typically worn during the Halloween season. These concepts can range from realistic depictions of monsters and supernatural entities to abstract representations of disturbing psychological states. An example is a mask meticulously crafted to resemble a decaying zombie, complete with rotting flesh and vacant eyes.
The significance of frightening visages in Halloween celebrations stems from historical customs related to warding off evil spirits and commemorating the dead. Such traditions evolved, resulting in the modern practice of donning sinister disguises as a form of symbolic expression and entertainment. This practice provides opportunities for creative expression, social engagement, and the enjoyment of shared experiences centered around the themes of horror and the macabre.
