Dreaming of blowing air signifies provoking a problem or conflict. If you blow air onto the ground, it symbolizes revealing a secret or warning someone. Such dreams reflect your mental state and draw your attention to certain aspects of your life. If you are concerned about some secrecy, this may be a signal from your subconscious mind regarding that issue.
From Imam Muhammad Ibn Seerin's Dictionary of Dreams According to Islamic Inner Traditions â entry "Blowing" (page 44).
To blow into fire in a dream means kindling a conflict or exasperating and intensifying it. Blowing into the ground in a dream means unveiling a secret or reprimanding one who does not keep a secret. Blowing into the vagina of a woman in a dream means that she will become pregnant. Blowing the trumpet of resurrection in a dream means salvation of the righteous ones. Hearing the first sound of the trumpet of resurrection in a dream means announcing the truth or hearing shocking and worrisome news. Hearing the second blow of the trumpet of resurrection in a dream means exposure of secrets, recovering of the sick, release of the prisoners, reunion of beloveds, loss of one's capital invest ment or the flow of wealth.
