Islamic Interpretation of Dreams (Ibn-i Sirin):

If a sick person sees an undertaker washing and shrouding him in a dream, it means his death or relief from his agony.

An undertaker in a dream also means payment of one’s debts, or repentance.

If one sees himself washing a deceased person with boiling water in a dream, it means that the latter is suffering in hell-fire.
