Dreaming of being in a state of impurity indicates that you are shying away from some fundamental responsibilities. It may reflect neglect or rejection of certain aspects of your life. Perhaps you are avoiding important tasks or relationships that are essential for you. This dream serves as a warning that it is time to rejuvenate yourself and embrace your responsibilities.
From Imam Muhammad Ibn Seerin's Dictionary of Dreams According to Islamic Inner Traditions â entry "Junub" (page 236) â resolved via the equivalent "Impurity" entry.
In a dream, to be in a state of ritual impurity means that one is avoiding to comply with fundamental religious obligations. According to Islamic traditions, one must have ablution even if when pursuing any of his daily interests. Ifone sees himself performing his prayers without the required ritual ablution in a dream, it means corruption in his religious practices, though it also could be interpreted as committing oneself to serve God's religion. Being in a state of ritual impurity in a dream also could mean confusion. If one sees himself in such a state and finds no water to perform his ablution in the dream, it means adversities and inability to sustain one's needs in this world, or to satisfy one's aspirations in the hereafter. Washing oneself or washing one's clothes of impurity in a dream means paying someone his due rights. In-laws; (Adversities; Benefits; Brother in-law; Distress; Father-in-law; Mother in-law; Profits; Son in-law; Stress) Having in-laws in a dream for someone who does not have in-laws means strength, peace and tranquility.
