If you dreamed about a line on your forehead: Your dreams know no bounds, you may have to give up some of the things you want to do. To see a line on your forehead in your dream refers to chasing your dreams, solving problems and doing good things that will add meaning to life. If there is no line on the forehead in a dream, it is interpreted as rebelling against fate, being in a sleep of heedlessness and doing a bad deed that you will regret.
