Seeing him in a dream signifies attaining one's wishes in both worlds for one who is God-fearing; if he is not God-fearing, let him beware. If he sees him in a town or village, its people will receive widespread rain and prices there will become cheap. If he speaks to the dreamer or gives him something, he will attain blessing and joy and will enter Paradise, because he is the angel of mercy. Seeing Michael indicates fertility, provision, abundant blessings, the growth of crops and plentiful rain. Seeing him may signify hearing the birds and witnessing the banners [unclear in the source] if the dream does not occur in the rainy season. Seeing him signifies a trustworthy treasurer and one who manages the funds for public welfare. It may signify a king who is kind to his subjects and tender toward them, like a compassionate father. Seeing him may signify drought and lack of water. Seeing him may signify a barren woman's becoming pregnant and the easing of what is difficult. If a traveler at sea sees him, there is fear for him; or if on land, he may be held back from his journey, because he is in charge of the rains, and they halt movement. Seeing him, for one who is harmed by rain, means worries and troubles; for farmers, it means provision and profit. Whoever is transformed into the form of Michael will attain fertility and wealth, and his conduct will become good.
