Seeing an owl in your dream may symbolize a tyrannical ruler or a solitary, dangerous thief. The owl could reflect negative situations in your life, such as unemployment or feelings of fear and confusion. This dream serves as a warning that certain matters may be harmful to you, and if you are not cautious, they could create problems in your life.
From Imam Muhammad Ibn Seerin's Dictionary of Dreams According to Islamic Inner Traditions â entry "Owl" (page 314).
In a dream, an owl represents a tyrant ruler, or a haughty and a dangerous thief who works alone without helpers. An owl in a dream also means being unemployed, or aversion of fear and bewilderment. In a dream, an owl also represents a traitor. Ifone sees himself fighting with an owl in a dream, it means facing a fight with someone. An owl in a dream also represents a person without steadfastness or determination to do what is right. If an owl falls inside his house in a dream, it means news of someone's death. An owl also represents thieves hiding in the darkness and under the shade of ruins, and of being annoyed about having to make an effort to earn one's livelihood.
