Dreams dictionary: Sting
Dreams dictionary: Interpretation 1
To dream that you are stung represents some hurtful action or remark. The dream may be a pun on some "stinging remark". Although, you are not letting it show how it has affected you, the pain is making its way into your dreamscape. Alternatively, the dream may also be a metaphor for being in love.
Dreams dictionary: Miller Dream Interpretation
To feel that any insect stings you in a dream, is a foreboding of evil and unhappiness. For a young woman to dream that she is stung, is ominous of sorrow and remorse from over-confidence in men.
