Dreaming of a toilet generally signals a release from mental stress. It may also indicate the fulfillment of your basic needs. A toilet is a place where you reveal your secrets and can be alone for a while. Sometimes, it is seen as a space for hiding money or resources. This dream could symbolize the need to confront some uncomfortable aspects of your life.
From Imam Muhammad Ibn Seerin's Dictionary of Dreams According to Islamic Inner Traditions â entry "Toilet" (page 438).
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. A toilet in a dream also represents a guard. (Also see Bathroom)
