The «liminal space» is the most significant horror icon of the 2020s. In the 2010s, everyone was enamored with creepypasta monsters like Slenderman or video game characters like in Five Nights at Freddy’s. These days, the boogeyman is not lurking in the woods but exists in weird empty indoor swimming pools or undecorated abandoned office spaces. For those unfamiliar, this is the definition of liminal spaces given by the Liminal Space Wiki.
«The aesthetic known as a Liminal Space is a location which is a transition between two other locations, or states of being. Typically these are abandoned, and oftentimes empty – a mall at 4am or a school hallway during summer, for example. This makes it feel frozen and slightly unsettling, but also familiar to our minds.»
