If you saw that you killed a black insect in your dream: You can get ideas from people who have more information on the issues you do not understand or who have different minds, and you may be impatient and unsympathetic towards the person you love. To see that you kill a black insect in your dream means that you will remove the person who gives you trouble and disturbs your peace with your speeches, will lead a different life, will change your outlook on life and will feel spiritually peaceful. Killing black bugs also means getting rid of one's obsessions.
