#23: Makeshift Slide
It is truly amazing just how many references the Duffer brothers were able to fit into one show. Granted, there are 3 seasons (about to be 4!), but there are an impressive amount of easter eggs regardless. There must have been enormous thought put into every time someone sat down to write the script.
You might have noticed that at the beginning of the season that the film, Dawn of the Dead was playing. Robin, played by Maya Hawke decides to slide down the middle of the escalator instead of walking down them, which is exactly what happens in the 1978 film, Dawn of the Dead.
