From Imam Muhammad Ibn Seerin's Dictionary of Dreams According to Islamic Inner Traditions â entry "Hate" (page 203).
Hate and abhorrence are the cause of divisiveness and enmity between people, and people need one another in order for them to reach their common goal. If one sees himself suffering from despise, or if he hates someone in a dream, it means a bad omen for everyone involved. To hate someone who loves you in a dream means having perfidy, jealousy and rancor. Hatred in a dream also may connote wanting to do what is right and abstaining from what is wrong. (Also see Grudge)
