Dream about being bitten by a venomous snake

No. The dream provides no evidence about anyone's real intentions, or whether a specific person is going to betray you. Snakes have long been linked symbolically to betrayal, so if it lines up with a doubt you already had, it may be worth examining that doubt while awake, with real information — not treating the dream itself as evidence.

A recurring dream isn't dangerous by itself, but if it keeps coming back or leaves you deeply shaken when you wake up, it can help to talk to a psychologist or therapist. A mental health professional can help you explore what waking-life concern might be expressing itself through that image.

Traditional interpretation

In dream tradition, the snake is one of the most heavily loaded symbols, and its bite almost always marks a turning point. Artemidorus of Daldis, in the Oneirocritica, attended mainly to the dreamer's social standing and trade when interpreting venomous animals, linking a bite to hidden enemies, illness, or a sudden loss of power, depending on each consultant's circumstances. Chevalier and Gheerbrant, in their Dictionary of Symbols, stress the snake's double nature: bearer of both poison and wisdom, tied to death as much as renewal, precisely because it sheds its skin. Marie-Louise von Franz, in her chapter for Jung's Man and His Symbols, describes the snake as one of the oldest images of the instinctual unconscious, capable of erupting when a vital force has been ignored for too long.

Artemidorus of Daldis, Oneirocritica (2nd century AD) — Attended mainly to the dreamer's trade, social standing, and circumstances when interpreting bites from venomous creatures, linking them to hidden enemies, illness, or sudden loss of power depending on context.
Jean Chevalier and Alain Gheerbrant, Dictionary of Symbols (1969) — Describes the snake's dual symbolism as both poison and wisdom, associated with death and renewal because of its capacity to shed its skin.
Marie-Louise von Franz (chapter contributor), edited by Carl Jung, Man and His Symbols (1964) — In her chapter on the process of individuation, von Franz treats the snake as one of the oldest images of the instinctual unconscious, appearing when a vital force has been neglected.

Psychological reading

No. Dreaming that a venomous snake bites you does not predict that you will actually be bitten or that real venom threatens your body; it is an image your mind produces while you sleep, not a literal warning. Antti Revonsuo's threat simulation theory (2000) proposes that the sleeping brain rehearses scenarios of ancestral physical danger — predators, falls, poisons — as evolutionary training for reacting better to real threats, and the snake is one of the oldest, most reliably recognized threat cues in our species. Ernest Hartmann, in Dreams and Nightmares (1998), suggests that such vivid images work as an emotional metaphor: the bite can condense a sudden sense of vulnerability or danger you already feel while awake. If the dream keeps recurring or leaves you deeply shaken, talking to a mental health professional can help you explore it calmly.

Antti Revonsuo, The Reinterpretation of Dreams: An Evolutionary Hypothesis of the Function of Dreaming (2000) — Threat Simulation Theory: dreaming rehearses ancestral physical-danger scenarios such as predator attacks and envenomation, not social-evaluation threats.
Ernest Hartmann, Dreams and Nightmares: The New Theory on the Origin and Meaning of Dreams (1998) — Frames vivid threat imagery like a snakebite as an emotional metaphor that can condense a waking sense of vulnerability, without pinpointing one fixed cause.

Variants

The snake was hidden

In this variant you don't see the snake until it has already bitten you: it was camouflaged in the grass, under a rock, or along a path you thought you knew well. Unlike an attack from a large, visible animal, the danger here is quiet and almost invisible until the last instant, which often points to a threat that had been building on ground you assumed was safe.

The snake was inside your home

Here the snake doesn't appear in a forest or out in nature, but inside your own home: under the bed, in the closet, or coiled in a familiar room. Finding the danger right inside the space you associate with safety and rest echoes the traditional reading of the snake as a symbol of betrayal, or of a threat coming from someone close rather than a stranger.

The venom spreads slowly

In this version, the most unsettling part isn't the bite itself but feeling the venom afterward, spreading slowly through your body while you try to get help or reach somewhere in time. That sense of harm that is already inside you and taking its time often reflects a concern you've been postponing, something already affecting you even though you haven't fully recognized its scope.
