Why is The Sandman called 'sandman'?
Where did the idea of the sand come from?
It is believed that the sand in The Sandman's magical sandbag represents the grains of sand in an hourglass, which signify the passing of time and the onset of sleep. Others believe that the idea of the sand comes from the ancient Greek myth of Hypnos, the god of sleep, who is often depicted holding a poppy stem and sprinkling sleep-inducing dew or sand over the eyes of mortals.
