Dreaming of thirst indicates stagnation in business, a downturn in the real estate market, and unsold agricultural products. Thirst in a dream can also symbolize poverty, recession, or economic crisis. Additionally, it reflects your desires or lack regarding important aspects of life. If you experience this dream, it may suggest that you need to make some changes in your life.
From Imam Muhammad Ibn Seerin's Dictionary of Dreams According to Islamic Inner Traditions â entry "Thirst" (page 434).
In a dream, thirst represents stagnation of businesses, dullness of the real estate market and unsalability offarm products. Thirst in a dream also means poverty, slump, recession, or yearning for a beloved, desiring to be with him and missing him. Thirst in a dream also could represent religious corruption. If a thirsty person sees himself searching for water but could not find it in a dream, it means that he will escape from a misfortune. If one sees himself standing thirsty before a source of water or a well but cannot drink from it or reach it in a dream, it means that he will fail to reach his goal. Thirst in a dream also means being corrupt, or it could represent one's need to get married to preserve his chastity.
