Blood
Quick Answer
Unlawful money, a sin, or a lie. Bleeding can mean loss of wealth or health.
Classical Interpretation (Ibn Sirin)
Blood in a dream generally has negative connotations. It signifies unlawful earnings (Haram money), committing a sin, or a grievous lie. If someone dreams they are covered in blood without a wound, they are being accused of a lie or associating with unlawful money. Bleeding excessively from a wound signifies a severe loss of wealth, health, or a separation from a loved one.
Quranic Context
