Islamic Interpretation of Dreams (Ibn-i Sirin):
(Lavatory; Toilet) In a dream, a bathroom represents the nest of impurities or the seat of sufferings.
If one enters it in his dream it means that he will be struck with distress caused by women.
For heat and pruriency may develop in one’s privacy inside the bathroom.
If a person in distress comes out of the bathroom in his dream, it means relief from his depression.
