Following the European mythology, there's an hour between 12 to even 3 in the morning that's the witching hour. In Spain 12 is said to be the witches' hour, and 3 in the morning is the hour of Evil. During this time, the witches and demons appear and are more powerful. Although during the Middle Ages, any woman could be sentenced to death simply because not being like the rest and sometimes accused with no clues.
