Dreaming of semen signifies the potential for financial growth in your life. It symbolizes your creativity and productivity. If you see semen emerging from your reproductive organ in the dream, it indicates that money or resources may soon come your way. This dream could be a result of your hard work and efforts, leading to long-term improvement and stability for you.
From Imam Muhammad Ibn Seerin's Dictionary of Dreams According to Islamic Inner Traditions â entry "Semen" (page 379).
In a dream, semen represents a growing and a lasting capital, whether there is little or much of it. If one sees a drop of semen coming out of his reproductive organs in a dream, it denotes money that will surface. If the man's semen spatters over his wife in the dream, it means that he will buy her a new garment. Owning an earthenwarejar filled with semen in a dream means uncovering a hidden treasure, or becoming wealthy. Ifthe husband is spattered with the semen of his wife in a dream, it means that he will satisfy his desire for her and attain his purpose. Drinking water from one's own reproductive organ in a dream means lustfulness. If the husband sees a thick yellowish fluid flowing from his wife's sexual organ in a dream, it means that she will give birth to an unhealthy child. Ifa reddish fluid flows instead in the dream, it represents a short lived child. If it comes out as a black fluid in the dream, it means that such a child will grow to dominate the family and to be an unjust master of the household. The ovum of a beau tiful woman in a dream means happiness, wealth and children. Semen in a dream also means attaining one's goal, comfort, or wasting one's capital, divulging one's secrets, or the death of a child. If a farmer sees semen in his dream, it means that he will work on a barren land and make it fertile. (Also see Impurity; Sexual intercourse; Vagina)
