Seeing snot in a dream can symbolize a child, whether a son or daughter. If you dream of wiping your nose in someone else's house, it may indicate a potential marriage or a secret relationship with that family. Such dreams suggest complexities in your relationships or the possibility of new connections. Therefore, if you experience this type of dream, you should pay attention to the dynamics of your relationships.
From Imam Muhammad Ibn Seerin's Dictionary of Dreams According to Islamic Inner Traditions â entry "Snot" (page 399) â resolved via the equivalent "Nasal mucus" entry.
In a dream, nasal mucus means a son or a daughter. To blow one's nose in someone's house in a dream means marrying someone from that family, or betraying the house master by having a secret affair with his wife. If a mother blows her nose in a dream, it means that she will wean her child. If the wife of such a friend wipes the nasal mucus of her husband's guest in a dream, it means that she will betray her husband and carry the child of his friend. If one blows his nose in a dream, it also means paying a debt, or it could mean rewarding someone for a favor. Blowing one's nose and using someone's bed sheet in a dream means betraying him with his wife. Blowing one's nose in someone's handkerchief in a dream means betraying him with his house servant. Clearing one's nose from a nasal congestion in a dream means dispelling distress. Wiping and washing someone else's nose in a dream means concealing his secret life in front of his wife. Eating one's nasal mucus in a dream means cheating one's son in his money. A congested nose in a dream represents a pregnant wife. If a beast or a bird comes out of one's nose when he sneezes or blows his nose in a dream, it means that he will beget a son from a secret affair with a servant or an employee. If a sable comes out of one's nose in a dream, it means that he will beget a son who will grow to become a thief. If a pigeon comes out of his nose in the dream, it means that he will beget a girl that will grow to be insane. Blowing one's nose and using one's own shirt in a dream means committing adultery with a sacrosanct member of his own family or a blood relation. Ifone sees his nose gloppy with mucus in a dream, it means that his fecundity and sexual appetite will bring him many children. Nasal mucus in a dream also means an illness, a cold, charity or a will. (Also see Phlegm)
