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.
