What Does Dreaming of a Mosquito Mean?
Traditional Interpretation
In the tradition of Ibn Sirin and al-Nabulsi, the mosquito can point to a weak but persistent enemy who, despite its small size, causes real irritation, to gossips and tiresome people, or to the petty troubles that wear a person down. A multitude of mosquitoes in a dream can be considered the herald of small but constant vexations that exhaust the dreamer.
Psychological View
From a modern psychological perspective, the mosquito can be a symbol of the small, recurring worries occupying the mind, of minor stresses accumulating unresolved, or of a "buzzing," irritating person or situation in your life. This dream may be drawing attention to the tiny tensions you ignore but that gnaw at your unconscious.
By Context
Being Bitten / Stung by a Mosquito
Can indicate that someone has hurt you with their words or behavior, that a small insult or a barbed remark has affected you; a passing material or emotional strain may be felt.
Many Mosquitoes (a Swarm)
Can be a sign of small troubles arriving one after another, of gossip and envy surrounding you, or of a crowded environment that wears you down; patience and boundary-setting may be needed.
Killing / Driving Away a Mosquito
In a reading close to the Ibn Sirin tradition, can indicate defeating a person or problem that disturbs you, and being freed of an irksome situation.
For Single or Married People
For a single person, it may point to a persistent but insincere attention nearby; for a married person, to small disturbances at home, or to talebearers coming between the spouses.
