If you see your face turning red in a dream, it symbolizes your dignity and generosity. It may represent someone known for their good deeds. Feeling embarrassed or having a flushed face typically indicates your self-confidence and social standing. This reflects your inner qualities and highlights your position in society.
From Imam Muhammad Ibn Seerin's Dictionary of Dreams According to Islamic Inner Traditions â entry "Blushing" (page 44).
If one sees his face glowing with red or blushing in a dream, it means dignity, nobility and it could represent a person who is known for his good deeds. If the blushing of one's face is mixed with some white lines in the dream, it means strength and happiness. If one sees his face embellished with red cosmetic makeup in a dream, it means that he will commit adultery, and that he will be exposed thereafter. If one sees his entire body turning red in a dream, it means long sufferings and lack of success in his life. Glowing redness in one's face in a dream also means recovering from an illness, or the home returning of a traveller. (Also see Bashfulness)
Note: Islamic dream interpretation depends on the dreamer's circumstances and state. This is a general guide drawn directly from the source book.
