One real - life element in 'Beetlejuice' is the general perception of the afterlife. Different cultures have different ideas about what happens after death, and the movie seems to play with that. It also has elements of how people might interact with the supernatural. For instance, the way the living characters in the movie deal with the ghosts in their house is somewhat related to how people in real - life might be scared or curious about the presence of spirits. The movie takes these real - life feelings and ideas and exaggerates them for comedic and horror effect.
