Islamic Interpretation of Dreams (Ibn-i Sirin):
(Lavatory) In a dream, a toilet means relief from distress, satisfying one’s innate needs, a bathhouse, taking a ritual ablution, a place where one’s secrets are exposed, a place where one hides his money, a treasury, a coffer, a rest room, or a place to reflect. Washing the toilet’s floor in a dream means becoming poor.
A flooded toilet in a dream means distress, pregnancy, or prosperity.
To fall into a toilet in a dream means imprisonment. Pouring honey or milk into the toilet bowl, or urinating blood in a dream means sodomizing. Looking into the toilet bowl and finding blood in it in a dream implies that one engages in the forbidden sexual intercourse with his wife during her menstrual period.
Atoilet in a dream also represents a guard.
