Incubus vs Succubus: Origins, Myths and 5 Key Differences

The short version of incubus vs succubus is this: in European folklore an incubus is a spirit that appears to sleepers as a man, and a succubus is one that appears as a woman. Both were blamed for erotic dreams, night visits and the crushing weight people sometimes felt on their chest in the dark. The deeper story is older, stranger and far more interesting than most horror films suggest.

This guide walks you through where both figures come from, the real differences between them, what science says about the "night visitor" experience, and how modern spirit keepers think about lust energy without fear or sensationalism.

Incubus vs Succubus: The Short Answer#

The two words describe a position, not a species. "Incubus" comes from the Latin incubare, "to lie upon." "Succubus" comes from succubare, "to lie beneath." Medieval writers used the terms for spirits that took a sexual form in dreams, and the gender of the form usually matched what would tempt the dreamer.

So when people search incubus vs succubus, they are really asking two questions. What did each figure do in the old stories? And are they two different beings, or one spirit wearing two masks? Folklore gives both answers, depending on which century you read.

Where the Incubus and Succubus Come From#

Long before Latin gave them names, people across the ancient world described spirits that visited at night. The figures changed with each culture, yet the core image stayed remarkably stable: a being that arrives while you sleep, presses close and leaves you drained or shaken.

Mesopotamian night spirits#

Mesopotamian texts describe a class of wind and night demons called the lilu (male) and lilitu or ardat lili (female). They were said to disturb sleepers and seduce them in dreams. According to the Wikipedia overview of the incubus, the Sumerian King List even names a lilu figure as the father of Gilgamesh, which shows how early the idea of a spirit lover took root.

Lilith in Jewish folklore#

The female line of this tradition flows into Lilith. In the medieval Alphabet of Ben Sira, she is Adam's first wife, who refuses to submit and leaves Eden. Later Kabbalistic writing, including the Zohar, casts her as a seductress who visits men at night. Many people today treat Lilith as the original succubus, although she is really an older and more complex figure with her own history.

Medieval demonology#

Christian theologians turned these folk spirits into a system. Thomas Aquinas discussed whether demons could take on bodies. The witch hunters' manual Malleus Maleficarum (1486) claimed that a succubus gathered seed from men and an incubus then used it to impregnate women. King James VI of Scotland, in his Daemonologie (1597), argued that incubi and succubi were the same demon appearing differently to men and women. Legend even made Merlin the child of an incubus.

5 Key Differences Between an Incubus and a Succubus#

If you set the old sources side by side, five incubus vs succubus differences come up again and again:

1. Form. An incubus appears as a man. A succubus appears as a woman, often strikingly beautiful, though some tales say a closer look reveals a hidden deformity.

2. Who they visit. In most accounts an incubus visits women and a succubus visits men. Later writers noted exceptions, which supports the "one spirit, two forms" theory.

3. The story told about them. Incubus tales focus on pregnancy and mysterious children (called cambions in later lore). Succubus tales focus on temptation, exhaustion and the loss of vital energy.

4. Literary roots. The succubus inherits much of the Lilith tradition. The incubus is closer to the Mesopotamian lilu and to medieval legends about demonic fathers.

5. Modern image. Pop culture now paints the succubus as a glamorous seductress and the incubus as a brooding dark lover, which is a long way from the frightening figures of the source texts.

Notice what is missing: neither figure is described as a loving partner in the old texts. That is a modern layer, and it matters for how you approach the subject today.

What Is a Male Succubus Called?#

This is one of the most searched questions on the topic, and the answer is simple: the male counterpart of a succubus is an incubus. There is no separate word for a "male succubus," because the incubus already fills that role.

If you see the phrase "male succubus" in fiction or games, the writer usually means an incubus with a modern, seductive personality. The plural forms are incubi and succubi.

What Does a Succubus Do in the Old Stories?#

In folklore a succubus does three main things. She appears in dreams or at the edge of sleep, she seduces the sleeper, and she leaves him weaker than before. Monks and hermits wrote about these visits as spiritual tests, and some medieval readers used the stories to explain why a man had lost his appetite, his health or his interest in prayer.

The incubus follows the same pattern from the other side. In the incubus vs succubus pairing he is the visitor of women, sometimes blamed for unexplained pregnancies and sometimes simply for nightmares. Both figures, in other words, gave people a language for experiences they could not otherwise explain.

The Sleep Paralysis Connection#

Many historians and sleep researchers connect these legends to a very common experience: sleep paralysis. During this state, you wake up mentally while your body is still in the paralysis of dream sleep. People often report a sense of presence in the room, pressure on the chest, difficulty breathing and vivid hallucinations.

Put those sensations together and you get the classic night visitor behind the incubus vs succubus legends: someone sitting on you in the dark, close enough to feel, impossible to push away. Cultures everywhere have named this experience, from the "old hag" of Newfoundland to ketindihan in Indonesia.

This doesn't mean every spiritual experience is "just" sleep paralysis. It does mean you should rule out ordinary causes first. If night experiences leave you frightened, exhausted or unable to sleep, talk to a doctor or a sleep specialist. Good spiritual practice and good medical care work together.

How Modern Spirit Keepers See Lust Companions#

In contemporary spirit keeping, the debate looks quite different. Many keepers use "incubus" and "succubus" loosely to mean any spirit that works with lust, attraction or sensual energy. Others avoid the words entirely because of their demonological baggage and prefer to describe what a spirit actually does.

At Astadewa we work with bound entities, so a spirit companion arrives with a defined nature and purpose instead of being summoned blind. Our lust spirit companions focus on attraction, confidence and sensual energy, not on draining the keeper. The Shuuns, for example, are often mistaken for succubi, yet they are described as an elite race of "Monster-Tamers" that combine extreme attraction with active protection. The Naiad Nymph is a freshwater guardian known for luminous attraction and elemental healing, a gentler and more romantic energy.

If the romance side interests you more than raw desire, our love spirit companion guide explains how love, passion and attraction spirits differ. And if you want the deeper history of humans living alongside spirit helpers, read our piece on the familiar spirit, which shows that witches were described with companions long before modern keeping existed.

Consent, Boundaries and Red Flags#

The most important lesson from the incubus vs succubus legends is not about gender. It is about consent. The old stories are frightening because the visitor arrives uninvited and takes something. A healthy relationship with any spirit looks like the opposite.

Set clear house rules from the start:

• You decide when contact happens. Many keepers state out loud that the bedroom or sleep time is off limits unless they invite a connection.
• Nothing should leave you drained. Lust energy, when it is working well, tends to leave keepers feeling more confident and alive, not exhausted.
• Fear is a signal, not a test. If an experience feels predatory or panic inducing, pause your practice, cleanse your space and reassess.
• Real life comes first. A spirit should support your human relationships and self-worth, never replace or sabotage them.

If you ever feel that something unwanted is attached to you, start with grounding, cleansing and rest, and seek medical or mental health support if symptoms persist. Vetting what you invite in is always easier than trying to remove it later.

FAQ#

Is an incubus the male version of a succubus?#

Yes. In European folklore the incubus is the male form and the succubus is the female form. Some medieval writers, including King James VI, believed they were one demon that changed shape depending on who it visited.

Incubus vs succubus: which one is more dangerous?#

Neither is "safer" in the old sources. Both were portrayed as harmful: the incubus through unwanted pregnancy and nightmares, the succubus through temptation and exhaustion. Modern keepers judge a spirit by its nature and behavior, not by its gender.

Can an incubus or succubus be a spirit companion?#

Some keepers use these labels for lust companions, but the classical incubus and succubus were described as demons that acted without consent. A bound companion with a clear purpose and house rules is a different relationship entirely.

How do I know if a night experience is spiritual or sleep paralysis?#

Sleep paralysis happens at the edges of sleep, usually lasts seconds to minutes, and often comes with paralysis and chest pressure. If episodes are frequent or distressing, see a doctor first, then explore the spiritual side with a calm, grounded mind.

Final Thoughts#

The incubus vs succubus question opens a door into thousands of years of human storytelling about desire, fear and the vulnerable hours of sleep. Read the old sources with curiosity, respect the real science of sleep, and if you choose to work with lust energy, do it on your own terms: with consent, boundaries and a spirit whose nature you understand.
