Dreaming of oneself bathing in cool water may refer to Allaah’s acceptance of one’s repentance, a cure from sickness and the lifting of a calamity, according to the following verses from the Qur’aan referring to Prophet Job (Ayyoob). Sharh as-Sunnah, vol.12, p.220. “This is a cool water to bathe in and a [refreshing] drink. And I returned his family to him, and along with them a similar number [of additional offspring].” Soorah Saad (38): 42-43
