The song "Hyoscyamus Niger" by Mystifier tells the story of a wicked old witch brewing a potion that will be used by her companions to conjure demons and foresee prophecies. The potion, made with the terrifying drug called Hyoscyamus niger, causes those who consume it to have hallucinations and be tormented by abominable creatures. The lyrics describe how the potion brings great pressure to the heads of those who take it, causing their eyelids to swell and forcing them to see visions in a faraway sense. Witches and wizards use the drug when they fall asleep, leading to them being surrounded by fantastic apparitions and tormented by satanic entities. The song paints a dark picture of the effects of the potion and the sinister activities of witches and wizards. It is a cautionary tale about the dangers of seeking power through nefarious means.
