I think that's based on spells in the manner of Shakespeare's Macbeth, Saliha.
Thanks for your answer.
I was thinking same yesterday that they have some similarities but just some:
the Three Witches in Shakespeare's Macbeth
All:
Double, double toil and trouble;
Fire burn and cauldron bubble.
Second Witch:
Fillet of a fenny snake,
In the cauldron boil and bake;
Eye of newt, and toe of frog,
Wool of bat, and tongue of dog,
Adder’s fork, and blind-worm’s sting,
Lizard’s leg, and howlet’s wing,
For a charm of powerful trouble,
Like a hell-broth boil and bubble.
So Halloween-style this poem anyways.
