Snake bite
Psychological (Freud)
In depth psychology a snake bite is often read as the sudden eruption of repressed instinctual forces or a wounding encounter that catches the ego off guard. The serpent itself carries a double charge of seduction and threat, so the bite may touch both fear and suppressed desire at once.
Oriental reading
In the tradition of Ibn Sirin, the snake is often a hidden enemy, and its bite warns of betrayal or harm coming from someone close at hand. Some interpreters gauge the scale of the looming enmity by the bite's severity, while a bite one recovers from may point to an attack that was repelled.

Dream interpretation is for self-reflection and entertainment — it is not a medical or psychological diagnosis.
