Spittle
Spitting against a tree in a dream means to recant one's promise. Spitting at another person in a dream means despising him. Warm saliva in a dream means long life, while cold saliva represents a short life. The color of one's saliva in a dream shows the state of one's spirit. Spiting blood or phlegm in a dream means speaking ill of others.
Dream interpreter: Ibn Sirin
