Seeing hemp in a dream reflects doubts, anxieties, and restlessness in your mind. It indicates that you are concerned about the legitimacy of your resources, earnings, or family relationships. Such dreams suggest that there are uncertainties in your life affecting your mental state. Therefore, it is essential to be mindful of your thoughts and feelings.
From Imam Muhammad Ibn Seerin's Dictionary of Dreams According to Islamic Inner Traditions â entry "Hemp" (page 208) â resolved via the equivalent "Intoxicants" entry.
In a dream, all intoxicants signify suspicions, apprehension and doubt about one's resources, or the lawfulness of his earnings, the legitimacy of his children, or the religious legality of his marriage. Drinking alcohol in a dream means losing a fight. Using drugs or intoxicants in a contemptible way in a dream signifies apostasy, loss of honor, negation of the truth, corruption of one's wife, or it could mean profanity. This is because the raw material and herbs used in the preparation of such drugs and herbs are sacred in their intrinsic state. Once mixed and taken to induce inebriety in a dream, they will produce the reverse effects. (Also see Drunk enness; Marijuana)
