The incubus and succubus of consciousness, are evil and unnatural creations.
According to Paracelsus, the incubus and succubus (which are male and female respectively) are parasitical creatures subsisting upon the evil thoughts and emotions of an individual on the astral body.

These terms are also applied to the superphysical organisms of sorcerers and black magicians. While these larvæ are in no sense imaginary beings, they are, nevertheless, the offspring of the imagination.

By the ancient sages they were recognized as the invisible cause of vice because they hover in the ethers surrounding the morally weak and continually incite them to excesses of a degrading nature.

For this reason they frequent the atmosphere of the dope den, the dive, and the brothel, where they attach themselves to those unfortunates who have given themselves up to iniquity.

By permitting his senses to become deadened through indulgence in habit-forming sex, drugs or alcoholic stimulants, the individual becomes temporarily en rapport with these denizens of the astral plane.

The incubus and succubus is the vampire, which is defined by Paracelsus as the astral body of a person either living or dead (usually the latter state). The vampire seeks to prolong existence upon the physical plane by robbing the living of their vital energies and misappropriating such energies to its own ends.

“A healthy and pure person cannot become obsessed by them, A healthy mind is a castle that cannot be invaded without the will of its master; but if they are allowed to enter, they excite the passions of men and women, they create cravings in them, they produce bad thoughts which act injuriously upon the brain; they sharpen the animal intellect and suffocate the moral sense.

Evil spirits obsess only those human beings in whom the animal nature is predominating. Minds that are illuminated by the spirit of truth cannot be possessed; only those who are habitually guided by their own lower impulses may become subjected to their influences.” ♋️
