If you feel an itch in your dream, it may signal poverty and a harsh lifestyle. Particularly if there is stress within your family, you might have concerns about certain aspects of your life. If the itch leads to blood or pus in the dream, it indicates that you will be able to achieve what you desire. This dream could serve as a warning regarding your current situation.
From Imam Muhammad Ibn Seerin's Dictionary of Dreams According to Islamic Inner Traditions â entry "Itch" (page 228) â resolved via the equivalent "Itching" entry.
In a dream, itching means poverty and suffering from the pressures of a demanding wife and children. If one's itching results in bleeding or puss in the dream, it means that they will get what they want. Otherwise, one's toiling for his livelihood will prolong. Ifone sees himself itching in a dream, it also means that he will investigate the conditions of his relatives and suffer from their state. If one's itching seems to last with no solution in sight in the dream, it means that he will suffer from a condition he cannot bear in wakefulness. If one sees people on the road afflicted with itching in a dream, it means that he will earn money but with a headache. A state he will become known by it. (Also see Mangy; Plague; Scratching)
