What real occultic imagery and themes? I mean really, not just what stupid D&D playing wiccans take from Greek mythology.
There is a difference between occultism and fantasy magic. One is waving a wand and yelling “Wingardium Leviosa” and the other is sacrificing virgins on a pagan altar. Neither accomplishes much but the second leaves more scars.

Mirrors as communication devices, automatic writing, astral projection, backfire curses, aura reading, generational witchcraft, spiritual posession etc.
