Here Petrus Dieleman explores how viewers construct meaning when confronted with their own shadow. He is seen as a pioneer in modern surrealism. We see a white shadow that doesn’t interact with the movements of the spectator and is, unusually, white instead of black. You might think this is a ghost. However, since ghosts have become extremely rare or possibly even extinct in our world, this is merely a representation of a ghost in the form of a shadow.
