The days before you set off on a journey somewhere, are the most important ones. In these nights, whatever dreams you get, may foretell your circumstances. If you dream that you were winding and rolling up loose thread/ yarn/ wool, it predicts that you are winding up loose ends. You will face such obstacles in your trip. In your waking life, you have foreseen tough obstacles and at night, your brain has created this dream, as a simulation of threat, or prediction of the time to come.
