Anti-Succubus/Incubus Spell
Spellcasting
A succubus is a demon or evil spirit that takes on the shape of a beautiful woman and seduces sleeping males in order to possess their souls.
An incubus is the male counterpart taking the form of a handsome man and seducing sleeping females.
For protection against a succubus or incubus, it is advisable to place mugwort under your pillow at night and recite the following incantation before going to sleep:
GODDESS OF THE NIGHT
WATCH OVER AND PROTECT ME
AS I SLEEP AND DREAM.
SHIELD MY SOUL FROM HARM
AND SHINE YOUR DIVINE LIGHT
TO KEEP AWAY THE SPIRITS OF EVIL.
